How dry I am

I was hot and sweaty while walking around the pits at Bonneville Salt Flats. I felt fine otherwise. I had cold water in the Rolling Steel Tent's fridge. I drank down a bottle before heading back to town and drank another as I drove. I've been craving water and guzzling it almost constantly since then. And peeing a lot, which probably wouldn't happen if I were dehydrated. I checked the symptoms.

I don't have a way to measure my blood pressure, but, except for the thirst, everything else on the list seems fine. Well, I've been confused my whole life, so that's "normal" for me.
