I hate hangovers & have tried many recipes. This is the simplest, most reliable and available method I have been using for the past several years. I discovered something like this in Europe and found a similar product here that works.
It's available at Walgreen's, CVS, Osco & some other drugstores too. It's called Chaser & you can buy a small pack or a larger bottle. It's homeopathic, contains only natural herbs and ingredients. Some of it is a big dose of B & C vitamins, which others have mentioned as helpful. Some of it is calcium carbonate & charcoal, which absorb toxins and is what they give to people in the drunk tank to bring them down. Some of it is various herbs & extracts such as lobelia & nux vomica, to combat headache & nausea.
It's best to take Chaser while you are starting to drink and not when you're already drunk, but if you realize you're getting too drunk or are about to, then you can still take it and it'll bring you down some. If you're pretty drunk before you take any, then you should be sure to stay up a while after your last drink and before crashing & drink lots of water [you should do that regardless anyway when drinking; I try to have a glass of water, no ice, for every alcoholic drink.] The only times it didn't work well were when people are already way drunk and maybe puking, didn't have much water or anything to eat, and then take it and pass out without staying up another hour or two till they felt better.
Unfortunately --It does NOT work the next morning when you're already hungover. But it has saved me from dozens of hangovers, in fact I usually feel pretty damn good the next day. I don't even take as many pills as they say you need to.
Here's a website about it for more info. And no, I don't work for the company, nor do I own any stock in this stuff. [Believe me, I tried to buy some stock after I tried it!] It just works that well, as long as you heed my advice on how to use it. I hope this helps some folks and let me know your experiences with it. Usually costs about $24 for 40 pills, and you need 1-4 pills for a night of drinking....but it's so worth it, you know. Sometimes I'd pay anything to kill that pain.

I have to thank you for starting this discussion because now that I looked up that website I see where you can order it for only $14 a bottle there! I'm ordering a couple right now!!!
