haha 21....i didn't wait till I was 21 to drink but I definitely got alcohol poisoning that night (first and only time).
I seriously threw up for 18 hours straight (about 10 minute intervals between).
Still it was a great night
I dont regret it at all I feel like it was a very college experience.
That being said alcohol is not a bad thing at all (and it's cheap especially on college campuses). I don't get drunk anymore i'm afraid those days are gone but I definitely enjoy going out with my team and having a couple beers. I'm decently social w/o it but I definitely know people who loosen up after a beer or two.
