Alcohol

Alcohol will often exaggerate whatever mood you're in when you start drinking.
Alcohol is a relaxant so, in moderation, it can reduce feelings of anxiety and inhibitions, making you feel more sociable.
It takes your body an hour to process one unit of alcohol.

One drink too many can leave you feeling out of control – like slurring your words, losing your balance and vomiting.
Official guidelines recommend that men shouldn’t regularly drink more than 3-4 units a day and women shouldn’t regularly drink more than 2-3 units a day.
Long-term excessive use of alcohol causes illnesses such as liver damage, stomach cancer and heart disease.
