Alcohol Addiction: Symptoms, Effects and Treatment

Written by the medical team at Day One Rehabilitation Center, Nakhon Nayok, Thailand · Medically reviewed by Dr. Pichayut Kasemphakdeephong (Psychiatrist)

Alcohol is a substance that acts on the brain and nervous system. Although drinking is common in society, continuous or heavy drinking can lead to cravings, dependence, difficulty controlling drinking, and alcohol use disorder, which affects physical health, mental health, work, finances, and family relationships.

Alcohol addiction doesn’t only affect people who are drunk every day. Some people can still work normally but need to drink every evening, gradually increasing the amount, unable to stop as intended, or experiencing hand tremors, sweating, palpitations, restlessness, and insomnia when they don’t drink — leading them to drink again just to feel better.

Families should know that alcohol addiction has specific treatment approaches, from medication to safely manage withdrawal symptoms, to medication that helps reduce cravings or prevent relapse alongside therapy. The goal of treatment, then, isn’t simply “managing to stop drinking” — it requires safely getting through withdrawal and having an ongoing treatment plan after stopping.

What Are the Signs of Alcohol Addiction?

With regular drinking, the brain and body can adjust to a continuous presence of alcohol. Some people therefore need to increase the amount to get the same feeling, and as alcohol levels drop, withdrawal symptoms begin to appear.

What started as drinking to socialize or relax can gradually shift into “I need to drink to fall asleep,” “I need to drink to feel normal,” or “I need to drink in the morning so my hands don’t shake.”

Signs to watch for include:

• Drinking more often or more than before

• Intending to drink less but being unable to stop

• Trying to cut down or quit multiple times but relapsing

• Cravings for alcohol

• Needing to increase the amount to get the same effect

• Drinking to help sleep or manage stress

• Continuing to drink despite emerging health, work, or relationship problems

• Periods of not remembering events while drinking

• Hand tremors, sweating, palpitations, anxiety, or insomnia when not drinking

• Needing to drink again to feel better after stopping

Alcohol addiction, then, isn’t judged by the number of drinks alone — it must be assessed by whether the person can control their drinking, whether they have cravings or withdrawal symptoms, and how much drinking has come to control their life.

Effects and Dangers of Alcohol

Continuous drinking can affect many body systems — the liver, digestive system, heart and blood vessels, nervous system, memory, sleep, and nutritional status.

On the mental health side, alcohol may be linked to depression, anxiety, mood instability, sleep problems, and difficulty controlling emotions. Some people start drinking to help them sleep or reduce stress, but with continued use, sleep and mood problems can actually become more complex.

If a co-occurring psychiatric condition is present, such as depression, an anxiety disorder, or bipolar disorder, it should be assessed and treated alongside the drinking problem — all symptoms shouldn’t be assumed to simply be the drinker’s personality.

In addition, while intoxicated, judgment, self-control, balance, and responsiveness all decline, increasing the risk of accidents and injury. If someone is unconscious and cannot be woken, breathing abnormally, having seizures, severely confused, or behaving in a way that could cause self-harm, they should receive emergency medical help.

Alcohol Detox: Why Some People Need Specific Medication

Detox, or care during alcohol withdrawal, is important because people who drink heavily and continuously may not be able to safely stop all at once.

Withdrawal symptoms can begin within several hours of cutting down or stopping drinking, and may include hand tremors, sweating, palpitations, anxiety, restlessness, nausea, insomnia, and elevated blood pressure. In severe cases, seizures, seeing or hearing things that aren’t there, or alcohol withdrawal delirium — a medical emergency — can occur.

Benzodiazepines: The Main Medication Used for Alcohol Withdrawal

In people with withdrawal symptoms or at risk of them, doctors may use benzodiazepine (BZD) medications, such as diazepam or lorazepam, to control withdrawal symptoms and reduce the risk of complications such as seizures and alcohol withdrawal delirium.

Using this medication doesn’t mean everyone who quits drinking receives the same treatment. A doctor must assess the severity of symptoms, drinking history, previous withdrawal episodes, liver disease, existing conditions, and use of other substances before selecting the appropriate type and dose of medication.

This class of medication must be used under medical supervision, because it can itself cause dependence, and combining it inappropriately with alcohol or other depressants can be dangerous. Sleeping pills or anti-anxiety medication should therefore never be bought and used to self-manage alcohol withdrawal.

For those who have been drinking heavily every day for a long time, who have had hand tremors after stopping before, who have had seizures, who have been confused during withdrawal, or who have a history of severe alcohol withdrawal, the process of quitting should begin as soon as possible, and they should be evaluated by a doctor to plan a safe way to stop drinking. Detox, or withdrawal management, is only about safely getting the body through the withdrawal period — it is not yet the complete treatment for alcohol addiction.

After Detox: Are There Medications to Reduce Cravings and Prevent Relapse to Drinking?

Yes. Treatment for alcohol addiction isn’t limited to medication for the withdrawal period. Once withdrawal symptoms have stabilized, a doctor can consider medication that helps reduce cravings or prevent relapse as appropriate for each individual.

Examples of medications used in treatment include:

Naltrexone, which helps reduce cravings and the pleasurable feeling from drinking, thereby reducing the likelihood of returning to heavy drinking in suitable patients.

Acamprosate, used to help sustain abstinence after completing withdrawal, suited to certain patients whose goal is continued alcohol abstinence.

Disulfiram, another medication that may be used in suitable patients — if alcohol is consumed while taking this medication, it causes an unpleasant reaction, so it must be used with clear supervision and understanding from the patient.

These three medications have different indications and precautions — not everyone is suited to the same drug. For example, naltrexone requires consideration of opioid medication or substance use, while acamprosate requires consideration of kidney function. The choice of medication should therefore be made by a doctor — patients should not buy and use these medications on their own.

Craving-reduction medication doesn’t replace therapy — it helps give patients a better chance of controlling cravings and sustaining their goal of abstinence, while therapy helps address the reasons and behaviors that lead back to drinking.

Therapy and Relapse Prevention for Drinking

After getting through withdrawal, treatment begins to look more deeply at “what is causing the need to drink.”

Some people drink because of stress, some drink to help them sleep, some drink when lonely, facing relationship problems, or in social circles where alcohol is always present. If someone stops drinking without building new ways to cope, cravings can return when they face the same situations again.

Ongoing treatment may therefore include craving-reduction medication as appropriate, individual therapy, group therapy, stress management training, adjusting sleep, exercise, and treatment of co-occurring psychiatric conditions.

Triggers to prepare for include parties, friend groups they used to drink with, stress, relationship problems, loneliness, insomnia, having alcohol in the house, or the thought that “it’s been so long since I stopped — just one drink won’t hurt.”

If relapse occurs, it doesn’t mean the entire treatment has failed. Instead, the person should look back at what happened before drinking, whether the current medication is appropriate, what triggers still haven’t been managed, and what part of the treatment plan should be adjusted.

What to Do When a Family Member Is Addicted to Alcohol but Won’t Admit There’s a Problem

A drinker may say, “I’m not addicted,” “I can still work,” or “I can stop whenever I want.” Arguing to force them to admit they’re addicted can turn the conversation into conflict.

Families should start from what can be observed — for example, “Lately I’ve noticed that when you don’t drink, your hands shake and you need to drink again to feel better, so I’m worried about the withdrawal symptoms,” or ask, “Have you ever tried to cut down and actually managed to do it as planned?” and “If drinking continues like this for another year, what do you think will happen to your health or work?”

The first goal doesn’t have to be getting the other person to admit to being “addicted to alcohol” — it can simply be agreeing to an evaluation of whether they have become dependent on alcohol, and if they need to stop, how to do so safely.

If the drinker isn’t ready, the family can consult a specialist first, especially if withdrawal symptoms are suspected. Confiscating alcohol or forcing someone to stop immediately to “prove” they can quit should not be used as a method.

Alcohol Treatment at Day One Rehabilitation Center

Day One Rehabilitation Center provides residential treatment, beginning with an assessment of the amount and frequency of drinking, duration of drinking, withdrawal symptoms, history of seizures or severe withdrawal, physical conditions, current medications, use of other substances, and co-occurring psychiatric conditions.

During detox, the treatment team monitors symptoms and vital signs, with a psychiatrist considering medication to manage withdrawal symptoms, such as benzodiazepines for those with a clinical indication, selecting and adjusting treatment based on each person’s risk. If severe withdrawal or complications requiring hospital-level care arise, the team will arrange a safe referral.

After getting through withdrawal, a psychiatrist can assess the appropriateness of craving-reduction or relapse-prevention medication, alongside individual therapy, group therapy, treatment of co-occurring psychiatric conditions, exercise, and adjusting routine and sleep.

Residential care also helps separate the person in treatment from alcohol and triggers during the early period, giving them time to practice managing cravings, stress, and high-risk situations before returning to real life.

The goal, then, is not simply “getting through withdrawal symptom-free,” but ongoing care as a single continuous process — from detox, to considering relapse-prevention medication as appropriate, to therapy, through to planning relapse prevention.

Frequently Asked Questions About Alcohol Treatment

Is it dangerous to stop drinking suddenly?

People who drink heavily and continuously can develop severe withdrawal symptoms after stopping, such as seizures or delirium. If someone has been drinking daily for a long time, has had withdrawal symptoms before, has had a seizure, or has been confused after stopping, they should be evaluated before stopping drinking.

What medication is used for alcohol detox?

Doctors usually consider benzodiazepine medications to control withdrawal symptoms and prevent complications in patients with a clinical indication, but the specific drug, dose, and duration must be assessed individually. Sleeping pills or anti-anxiety medication should not be used to self-manage alcohol withdrawal.

Is there medication to reduce alcohol cravings?

Yes, such as naltrexone, which helps reduce cravings and the likelihood of returning to heavy drinking, and acamprosate, which helps sustain abstinence from alcohol in suitable patients. A doctor will assess which medication is appropriate based on the patient’s health and treatment goals.

Does completing alcohol detox mean someone has recovered from addiction?

Not yet. Detox is care for the period when the body adjusts after stopping alcohol, but cravings, triggers, drinking behavior, and co-occurring conditions still need continued treatment.

Why do people relapse after quitting alcohol?

Relapse to drinking can be caused by cravings, stress, insomnia, friend groups, the environment, or co-occurring psychiatric conditions. Treatment must therefore include a relapse prevention plan, and some patients may also benefit from medication to reduce cravings.

Can alcohol addiction be treated?

Yes, it can. Treatment may include safely managing withdrawal, medication to reduce cravings or prevent relapse, psychological therapy, treatment of co-occurring conditions, and adjusting the environment as appropriate for each individual.

Quitting alcohol isn’t just about stopping drinking — it requires ongoing treatment.

Families don’t need to wait for severe physical illness, job loss, or dangerous withdrawal symptoms before seeking help. If you start to notice increased drinking, an inability to control it, hand tremors when not drinking, or repeated attempts to quit followed by relapse, the starting point should be assessing the severity of the addiction and the safety of stopping drinking.

Alcohol treatment today involves far more than simply telling patients to endure it and quit on their own — it includes medication to manage withdrawal, medication to reduce cravings and prevent relapse, and therapy to address stress, triggers, and mental health issues. Choosing the right approach for each person means the goal isn’t just getting through detox, but returning to a life that doesn’t depend on alcohol.
