be careful and watch your salt intake. Dehydrating yourself for a dry look during a competition can be very strenous on ur body. the lights, and heat, and posing, and low water can rise problems, and possibly black out.

what ever you do, play safe and make sure you have water/electrolyte drink nearby.. Pedialyte is good for this, i had many athlete friends drink this during football 2adays to prevent cramps and dehydration.

I like doing a gatorade/powerade and water mix, 1 to 1. So if i have 20 oz -ade, i add 20 oz water. you prolly have a good knowledge on diet and such so just be smart.
