Don't start bingeing, those people who drink a whole bottle of vodka tend to also be the ones who can't remember a thing about the night and vomit a LOT.
Just drink what you like, and get to know your limits. I tend to go for a bottle of wine before I go out and don't drink anything once I'm there because I know that I'll be pretty drunk, but won't be ill in the morning. Unless I decide it's a good idea to shots at the club, then I spend some of the morning by the toilet (doesn't happen often, as our chunder chart proves).
