I do know what you are talking about as far as getting used to using less water.
The Indians out here in desert SW had a cross country competition where they would run 5 miles with a mouth full of water. When they finished the 5 miles they had to spit out the water. The Indians and their horses also could outlast our cavalry in chases during the summer. I am a wimp for water.
