little late posting this....

I swear by Emer'Gen'C. I put a packet into each nalgene after giving the purification tabs to do their thing. Electrolytes, vitamin C (I think the C stands for crack, a dose of it always improves my mood), A, B-complex, and just enough sugar for your body to actually be able to use it.

The only use I have for gatoraid anymore is for "wake-wake juice"- pout a packet of Emer'gen'c into a nalgene bottle, then a 12oz can of Mt Dew, and a 20oz bottle of organe gatorade. You are painfully awake in about 20 minutes, but if you use it to wash down a couple asprin, the hangover starts to go away.
