Yeah alcohol is good and all, but it's easy to have too much if you aren't an experienced drinker/can't stop drinking even when you've had enough. I'd say have a drink or two, nothing major, and just try to force yourself to go out on a limb a bit. Being around drunk people can be good because they will be more open, but you also don't want to be meeting people who are completely out of it because they won't be the best conversationalist.
