Hair of the dog that bit ya works awesome but I guess not if you have to roll into work. Other than that preemptive hangover remedy works best drink several glasses of water and a couple aspirin before going to bed. In short... You're Fucked and have to ride it out. :lol

Edit: Almost forgot Alkaseltzer sometimes works unless you were chasing 2 for 1 Heines with shots of THE JGERMEISTER. Then you should just shoot yourself and put yourself out of your misery. :rollin
