Trying to be good/drinking with my peepsH

I'm trying to be good today, because I want to go drinking with my peeps tonight. From what I hear the place we're going serves beer and wings and not much else. I figured if I wanted to eat 6 wings and drink 2 beers, I'd be at around 600 calories for the excursion. SO I had a salad and some steamed asparagus for lunch. I couldn't finish it. I WANT THE FROZEN PIZZA! I WANT MEAT! I WANT ICE CREAM!

I suppose I could go take a walk or dance around the house or do yoga or SOMETHING, so I can at least eat a bit more and stop feeling hungry right now. I really should. I don't really want to, but I don't want to feel hungry either. *GAH* I suppose an empty stomach is going to have to be motivation enough. *sigh*

Thanks for listening to this sort of rant, and any input you guys/gals have is most welcome. How would you deal with this situation?
