Depression after quitting alcohol: why it happens, how long it lasts and when to get help

Feeling low after you stop drinking is common and often lifts within weeks. Why it happens, how long it lasts, what helps and when to get help.

Quick answer

Feeling low or depressed after you stop drinking is common, and for many people it lifts within a few weeks. In a study of 191 men in treatment for alcohol dependence, 42% were clinically depressed when they started and 6% four weeks later. Drinkaware says alcohol is a depressant, and that cutting it out for four weeks often makes a clear difference. If low mood lasts more than a few weeks, see a GP. If you feel you might harm yourself, call 999 or go to A&E now.

If you feel you might harm yourself, get help now. Call 999 or go to A&E. In the UK you can also call Samaritans free on 116 123, at any time of day or night. Outside the UK, call your local emergency number or a crisis line in your country.

Why you can feel depressed after you stop drinking

It seems backwards: you have done something good for yourself, and you feel worse. There are a few reasons.

Alcohol is a depressant. The UK charity Drinkaware says alcohol "alters the delicate balance of chemicals in your brain", and that drinking heavily and regularly is linked with depression. Your brain needs time to settle without it.

Alcohol may have been covering something. Drinkaware warns that people who rely on alcohol to mask feelings of depression can become reliant on it. When the drink goes, those feelings are still there, often sharper for a while.

For some people, the depression came first. A large US study of 2,945 people with alcohol dependence found that 26.4% had had at least one episode of depression caused by their drinking. Another 15.2% had depression that began before their drinking problem, or during a long time without alcohol. That second kind is depression in its own right, and it can be treated.

Withdrawal and bad sleep play a part. Poor sleep and anxiety are common in the first weeks, and both drag mood down. Our guide to insomnia after quitting alcohol covers what helps with sleep.

How long does depression last after quitting alcohol?

For many people, weeks rather than months.

Most of it lifts within four weeks. A US study followed 191 men through inpatient treatment for alcohol dependence, none of whom had a mental illness before their drinking. When they started, 42% were clinically depressed. Four weeks later, 6% were.
The biggest change came by week two. Low mood eased fastest. Physical symptoms, such as poor sleep and appetite, took longest to go.
It takes about three weeks to tell the two kinds apart. A later study by the same team found that depression caused by drinking eased faster than depression that came first, and that it took at least 3 weeks without alcohol before doctors could tell which was which.

That is why the Royal College of Psychiatrists, quoted by Drinkaware, says it is usually best to deal with the alcohol first, and then with the depression if it has not lifted after a few weeks. Drinkaware says many people who are depressed find that four alcohol-free weeks make a clear difference.

Our timeline of what happens when you stop drinking shows where mood fits among the other changes.

What helps

Give it a few alcohol-free weeks. Drinkaware says reducing or stopping drinking can improve your mood, and that drinking when you already feel low can make it worse. A drink may feel like it would help tonight. It will not help next week.

Tell someone. The NHS suggests letting family or friends know what is going on for you.

Move a little every day. The NHS lists more exercise among the lifestyle changes that help many people with depression. A walk counts.

Look after your sleep. The NHS lists sleeping badly and feeling constantly tired among the symptoms of depression, so sleep is worth working on alongside mood.

Find people who understand. The NHS says joining a support group is worthwhile, and suggests sharing your experiences with others in a similar situation.

If you are prescribed antidepressants, Drinkaware says not to drink any alcohol without checking with your doctor or pharmacist first.

When to get help

Right now, if you have harmed yourself or feel you might: call 999 or go to A&E (or your local emergency number). The NHS also suggests getting yourself to a safe place, being around other people and staying away from alcohol and drugs.

See a GP if you have felt low for most of the day, every day, for a few weeks. Drinkaware suggests telling them how much you drank, or how long you have been alcohol-free. A GP can offer talking therapy such as CBT, a support group or medicine. The NHS says that with the right treatment and support, most people with depression make a full recovery.

Before you stop: if you drink heavily every day, speak to a doctor or a local alcohol service first. Stopping suddenly when you are dependent on alcohol can be dangerous.

Questions

Is it normal to feel depressed after quitting alcohol?

Yes, it is common. Alcohol is a depressant, and the brain needs time to settle without it. In a study of 191 men in treatment for alcohol dependence, 42% were clinically depressed when they stopped drinking. For most of them, it had lifted within four weeks.

How long does depression last after quitting drinking?

Often a few weeks. In that study, the biggest improvement came by week two and only 6% were still depressed at week four. If low mood lasts longer than a few weeks, see a GP: for some people the depression was there before the drinking and needs its own treatment.

Why do I feel worse after I stopped drinking?

Alcohol changes brain chemistry, and it may have been covering feelings that come back once it is gone. Poor sleep and anxiety in the first weeks also lower mood. For most people this eases, but tell someone and see a GP if it does not.

Should I see a doctor about depression after quitting alcohol?

Yes, if you have felt low most of the day, every day, for a few weeks, or straight away if you have thoughts of harming yourself. Tell the doctor how much you drank and how long you have been alcohol-free.
