Drink, drink, drink dude...
I'm in the field alot this summer in Houston, Texas with temps of 95-100 degress with 95% humidity. Unreal how horrible it is really.
For instance today, I drank 8 liters of water and didn't piss one time.
Don't try to be a tough guy. If you've really had heat stroke, which I have, you wouldn't be trying to prove anything. Work hard but drink. Water only does it for me until lunch. Then it's replentishing electrolytes time.
