I'm going to post this here because it just came up in another thread, and if I'd been really smart, I'd have posted it someplace before New Year's Eve.

For those of you who drank--or are still drinking--to celebrate the New Year, please avoid taking Tylenol or any other over-the-counter medicines containing acetominophen to help your hangovers. In America, they're about to put warnings on aceominophen bottles about its dangers with alcohol (or within 12 - 24 hours of consuming alcohol). When combined with alcohol or taken within a day or so of drinking, acetominophen can cause really bad liver damage and sometimes even liver failure. This isn't as well publicized as it should be, and it's a potentially very dangerous combination. Just an FYI! Take aspirin if you need to take something for hangover headache, and avoid ibuprofen, too. Ibuprofen in combination with alcohol can increase your risk for stomach bleeding.
