I saw that headline in my RSS feed and was immediately intrigued. Sadly, the answer is, “Nobody knows.” But it’s a sad answer with an interesting reason behind it. Turns out, hangover cures are one of those things that have never gotten much attention from science, according to the Good, Bad and Bogus blog. And, apparently, that’s because doctors view hangovers as a complication of excessive drinking, rather than a medical problem in, and of, itself. Treating hangover is controversial because there’s already a cure, according to an editorial in Current Drug Abuse Reviews: Don’t drink so much.
