this showed up on blogdex. an article in the new scientist giving a little primer on the renal physiology of ethanol, and suggests just exactly how much water you need to drink in order to prevent a hangover.

some people swear by pedialyte, but it tastes like chalk. if you did an electrolyte analysis, gatorade is close enough anyway, and it tastes a lot better. but the only known cure for a hangover is 2L of normal saline or lactated ringer in your veins. (at least, this is how doctors survive a heavy night of drinking. so i've been told.)
