Prevention - drink less, or not at all. Most of the "I'm still going to drink, but I don't wan't a hangover" advice is subjective, everyone's chemistry is different, and what works for you may not work for me and vice versa...or versa vice-a. Also, half the advice you get is going to be forgotten or ignored once the booze gets flowing. Now cures (also highly subjective imo) on the other hand, I've tried them all. I'll rank them for you, because I'm a nice fucking guy, and I got class. 1) Pedialyte - Or as I like to call it "Miracle Water." I am found of the "Cherry Punch." It has more potassium,more sodium, less carbs, and less calories than Gatorade. It doesn't leave me feeling as bloated as Gatorade either. I like it cold, and I'll slam about half the the bottle (15 oz) then sip the rest. I start feeling better shortly thereafter. 2) Exercise/dry sauna/spa - I know it sounds nuts, but if you can get out the door to the fitness center, do it. Its a tall order to get on an elliptical, or a treadmill, but that and a good 10-15 minutes in a sauna will work wonders. I usually do the pedialyte then hit the fitness room. 3) Hair of the dog - This happens most of the time when I've had a really late night; meaning coming in at 8 or 9 a.m. I come from a long line of insomniacs, that require little to no sleep, so even if I haven't slept in 24 hours - a 3 or 4 hour "party nap" as I like to call it is sufficient. That doesn't negate the fact that I may be hungover and experiencing all the dreaded symptoms; headache, dizziness, dehydration...In these situations when I see Vegas time is slipping away, it's time for a shot and usually a index finger size line of cocaine. Viola! Life is good and to the tables we go. Hope this helps.
