^advices from my personal experience
• Don't fill up on beer, you feel shitty and prone to have a hangover. If you do have some vodka it helps.
• Hard liquor is king.
• Eat some food before and after, your stomach can burn like a bitch if you don't.
• Enjoy yourself don't get sloshed because everyone else is, just get a nice buzz and keep it going the whole night.
Make sure you eat before you start drinking, but not too much. Also be sure to pace yourself after every shot, maybe starting with 3-4 in a short time is okay (for a male, females tend to get drunk quicker) and then slowing down.
What I found out for myself is that everybody reacts to a certain type of alkohol for example I cant stand vodka for different reasons one of them is that its the only liquor I get sick from.
Second thing is that you have to control yourself. There is a point where you know its bad to drink more. Stop if you have that moment.
One thing I heard but I cant realy say that much about it is that you should never drink if you are sad.
