I have. I didn’t work. Of course, I drank A LOT more than the amount listed on the package, plus dehydrated myself worse with some… um…herbal assistance, so I can’t be sure if they work.
As for cures, I go with lots of water, a couple advil, something to eat and a very long, hot shower
Ruadh: I sympathize with you since I have been the victim of hangovers many times. However, we both know you will be drinking again soon. I offer a hangover prevention that has always worked for me: drink plenty of water, at least one quart, before going to bed. If you get up in the night, drink additional water. Hope your kidneys are strong.
Incidentally, after today I’m going to have to recommend against biking around for several miles in hot and humid weather while hung over. Something to do with dehydration, I’m assuming. Ugh.
