One thing is that usually no one notices if you are drinking or not. But whenever I go to a party/event, I usually carry around a glass of water/tonic water/Diet coke/whatever. That way I have my hand the same way as everyone else. Truth is, I usually end up annoyed at people who are drinking and just chat with a few people and leave when I can. It's actually not that fun - drinking... I look forward to my sober morning!
