there's a bunch of other things I can recommend for electrolytes, if Gatorade is the thing you hate most...

I like HEED, a Hammer product. They make a plain flavor which tastes like...water. You can find it at http://www.e-caps.com

NUUN is also good stuff, it's sugar free, just electrolytes, and the flavors are very mild. You can find it at

How are you with daily supplements (vitamins)?

As far as your other problems, I have no expertise to offer, only my empathy. That must suck deeply, I'm sure I would find it hard to be in your situation.
