+1 to what everybody else said.

But one other thing. When I have nonspecific symptoms like that, low fever, nausea, diarrhea, body aches, nine times out of ten it's primary dehydration.

I'm well aware I get dehydrated much easier than "normal" people.

But whether it's primary or secondary, dehydration can both produce *and* result from those symptoms.

So... slam that gatorade, or whatever your preferred hydration solution. Have a liter right this very second, just on account-a. Now have another. And a third before you go to bed. See if you don't feel better in the morning.
