There are some remedies and hangover cures out there that have worked great on me. Prickly pear I would say has been the best. There was studies done by an Arizona college proving its effectiveness with hangovers.
Recently I started using a hangover patch made by Zaca. The stuff works excellent! One of the ingredients is prickly pear, go figure. I just like how the patch is convenient, you put it one when you start drinking and it helps your body get nutrients WHILE your drinking so you don't get a hangover. Zaca's site is: www.zacalife.com
