Yep.
That's why I simply don't go to parties; that and at my age the invitations aren't flying in.
When I do go to parties, it's always with my wife, and I have the excuse of having to drive home, so I don't stay long and don't drink.
If I didn't have these responsibilities I would likely be sucked into staying around and would get drunk and make a nuisance of myself.
I can't make your decisions for you, but I can recommend you have a drink of water as at least every second or third drink; this will keep you hydrated, and will be annoying enough to you having to pee all the time that you'll be disinclined to overdo it.
By all means hang round the kitchen and talk to people you feel comfortable with, but don't allow the alcohol to control you; it's not like as if each party is the only chance you get to drink and you need to do it before it becomes illegal, enjoy and savour rather than down booze and get messed up.
If that's too hard, rationalise and only go to a few parties.
The other option is to really talk to those other people; you may find they are over the whole scene and you may find you can develop enduring friendships with those people outside of the party environment.
Regardless, if you go with the flow and don't obsess you may find the whole thing is a transitional part of your life, and 10 - 15 years or more from now you won't even remember why you felt how you do now!
That's been the case with me!
