If there were no hangovers, many of us would have very happy, albeit brief, lives. Here's to January 1, our collective morning after.
WHEN: After every drink
WHY: I can't imagine why. Following every alcoholic drink with a big glass of water does not prevent a hangover, it merely drowns your buzz. Farmers are good with regular, measured applications of water. Drunks are good with the regular, measured applications of booze. Show me an irrigated reveller and I 'll show you a sober person, most likely on his/her way to take a pee. The H2O hangover prevention theory is like suggesting that celibacy is the best way to avoid STDs.
AVAILABILITY: Your tap, where it's absolutely free
