Didn't read the entire thread but if nobody had mentioned it I would try Emergence-C. I personally think the stuff is great. It has quite a bit of vitamins in it, but more importantly it has the needed electrolytes and it's not sugary like gatorades, which the sugar makes me sick when it's hot. A box only runs about $10 (100 packets I think). so you only need to take what you need. And you can mix the servings as you need them instead of being stuck with just gatorade. I fight fire in the summer times and have seen alot of dehydration and run down sick bodies and this stuff has helped alot of people.
