Pedialyte works well, but it tastes like death and has too much sugar. that is the problem with other sports drinks too, they have too much sugar. Too much sugar makes it harder for your body to rehydrate.
I've tried Rapid Rehydration,(www.rapidrehydration.com
, and it works. It is basically like pedialyte except it doesn't tasate like crap and it has less sugar.
Also, don't eat chicken breasts or other heavy protien rich foods right after making weight. Simple, carbohydrate rich foods like oatmeal and other cereals are absorbed faster into your body and is what your body really neads.
