Yep, I've been SAG'd too for that reason. That's about the only reason I will stop, if I have been dumb and not kept my nutrition, hydration, and electrolyte intake at the proper levels, and the body just starts shutting down. I never want to have heat exhaustion again. There is something fundamentally WRONG with shivering in near 100 degree heat, not sweating, hallucinating, and feeling the constant need to throw up. BLEH.
