A few things can help:
-Drink extra water all day
-Do EXTRA cardio the day of the drinking and the day after (sweat it out
-Drink vodka, lime & soda (with fresh lime if poss), or vodka and diet coke
-Don't eat the crap food! Order a salad or something instead. If you're just going out for drinks, have a vege-full dinner before you go.
I think driving is a good idea! Oh and apparently white wine and lo-carb beers aren't too bad either.
