Alcohol can harm you in many ways and contributes to around 33,000 deaths every year.
After drinking too much alcohol, some people get a 'hangover' the next day. Symptoms of this can include being sick, diarrhoea, a headache and feeling down.
Short term effects of drinking alcohol can include losing consciousness, slow breathing and heartbeat, choking on your sick, and poisoning.
Longer term effects can include liver problems, cancer, strokes, high blood pressure, heart disease, brain damage, blurred vision, obesity and lots of mental problems.
On top of all these, alcohol affects your judgement, which can cause dangerous and harmful accidents. Around 17% of all deaths on the road are caused by someone drinking too much.
