Most of us have days when we feel a bit low. But for some people, these feelings don’t go away – they get worse and may start to interfere with everyday life. This is what’s known as depression and it’s very common: according to the Royal College of Psychiatrists, one in five of us will be affected by it at some point in our lives1.
Common triggers for depression include relationship problems, unemployment, divorce and bereavement. But people who drink heavily, regularly, may develop the symptoms of depression without having any of these problems.
Alcohol is a depressant: it alters the delicate balance of chemicals in your brain. As you sip your first drink, the alcohol starts to affect the part of the brain associated with inhibition. That’s why a drink can help you feel more confident and relaxed.
But as you drink more, something different can start to happen. Once your brain has high levels of alcohol affecting it, it’s possible the pleasant effects of your first drink will be replaced by negative emotions such as depression, anxiety or anger – even if you were in a good mood when you started drinking.
Regular drinking lowers your levels of serotonin2 – the brain chemical that helps to regulate your moods. This is one factor leading to symptoms of depression if you drink heavily and regularly.
In addition, alcohol and depression can feed off each other to create a vicious cycle. Regularly drinking heavily may affect your relationship with your partner, family and friends, or impact on your performance at work, making life feel difficult and depressing. And after a hard day, it can be easy to believe that having a drink will help.
If your depression symptoms are being caused by your drinking, stopping drinking should bring about a significant improvement. In fact, people in this position often find that cutting out alcohol entirely for just 4 weeks will produce a clear difference in how they feel2.
After a few alcohol-free weeks, many people find they feel brighter. You may find it less difficult to get up and face the day, and friends and family may find you easier to get along with.
To help prevent your symptoms returning, if you decide to resume drinking alcohol in the future, make sure you stick within the UK Chief Medical Officers’ low risk drinking guidelines: Don’t drink more than 14 units a week (that goes for both men and women), have several alcohol-free nights each week and avoid binge drinking.

If you’re still experiencing the symptoms of depression four weeks after cutting out alcohol, the Royal College of Psychiatrists advises that you talk to your GP. Remember to tell him or her how long you’ve been alcohol-free.
Your GP may recommend a talking therapy such as counselling or CBT (Cognitive Behavioural Therapy), or a self-help group. He or she may also prescribe you antidepressant medication. Remember, you’ll probably need to continue to avoid alcohol or only drink very lightly if this is to be effective.
