I don't drink unless I'm with friends, and even so I moderate it. I'll usually have a couple of beers, maybe a shot or two max and that's about it. I don't need to get drunk to have a good time. I suppose I could do with a buzz, nothing wrong with that. But getting drunk is just not a smart thing to do, especially when out on the town. With JUST friends, it's slighlty more justified, but I still wouldn't.
Plus, I seem to have a bit of a natural high/drunkenness to me anyways, so I don't particularly need to get drunk to have fun. The only problem is is that you can't really have fun when people are drunk and you are sober - if buzzed, you can pull it off.
