MDinana... Sorry, I misread your post.... the packet is G02 not G2 (regular not the low carb)

did a little testing of some of the formulations on the net..the concentrations are pretty close to the Gatorade formulas....you can come up with a DIY version using

sugarless Kool Aid
Mortons lite salt (potassium and sodium chloride)
sugar

most of the recipes are for a 2qt solution...what I use is less than the amounts of solutes in the posted recipes, and "real lemon" concentrate
