Always have something before drinking
Drinking alcohol is a bad habit. Everyone knows but you know, it becomes difficult for some people, because it is kind of fun to boost sometimes and also if all the friends are having drinks and I am not, then it would be quite boring. Anyway, this is my personal opinion and I am not trying to promote drinking. IT IS BAD FOR HEALTH.
But in any case, any circumstance, if you are suppose to drink, then take something, burger, hot dog, some salads or anything before drinking because drinking in empty stomach is just like pouring acids in your stomach. The chance of inner stomach lining wall ulcer is more if you follow the practice of drinking in empty stomach.
Of course, you are drinking alcohol to enjoy and celebrate and not to burn your stomach and ruin your health. So, if you want to continue enjoying, then it will be wise idea to follow some practices like eat something before drinking and have fun.
