The first time you get drunk is kind of different from the rest of the times. The first time, the first thing you'll feel is a kind of light-headedness and suddenly you start laughing for no apparent reason. You feel very relaxed and are enjoying the company of your friends. Also you'll start feeling a lot more talkative than usual.
As you continue to drink, these feelings become even more evident and what I remember from my first time being drunk is that it looks like everything is happening in a kind of slideshow in front of you. You don't really see the fluid motion of movement that you normally would, instead everything is in like snapshots.
Before you go to sleep, drink as much water as you can. And then drink even more water. Trust me.
