Put simply, drinking makes your brain cells shrink. Once the "feeling good" part of drinking is over, those brain cells will hurt. You need to rehydrate them, ASAP.

It really doesn't matter if you use Pedialyte, Gatorade, or Water - but once you've stopped drinking, start drinking (nonalcoholic) - lots and lots of them. Have a glass (or large bottle) next to your bed. When you wake up, drink more water. By keeping your brain cells properly hydrated, you will put off the pain, until there's no pain to put off any longer.

The only other scientifically proven method (which I've heard of) is a combination of throwing up before going to bed, then drinking lots of liquids as in above. It's good for bonding, too!
