WATER! it's all about being hydrated. When you start feeling drunk and all you want is another drink because you aren't drunk enough, get a water with your drink, and then another a few drinks later. If you can drink 3 or 4 glasses of water, or like 2 water bottles while you are drinking, and then have another glass before you go to bed, you should wake up almost like you never drank the night before, and you probably won't be able to sip through out the night, because you'll sleep like a baby.... well 'cept for maybe you'll get up to pee a couple of times, but it's better than the alternative.
