<p>I'm interested in doing multi-day hikes (i.e. backpacking) in the desert where water sources are not readily available, thus requiring one to carry in enough water for the duration of the trip.</p>

<p>On  any given day I feel the need to drink <strong>a lot</strong> of water, much more than most people that I know.  About a gallon in a typical relatively inactive (working at a desk) day.  If I don't drink this much water, I start to feel thirsty.  To do a multiday trip I will be drinking considerably more water (at least 1.5 gal/day?) which will become burdensome: this would mean 36 pounds of drinking water for a 3 day trip.</p>

<p>Like I said, I definitely begin to feel thirsty and dehydrated (dizzy) if I lower my current water intake much at all.  Is it possible to train oneself to require less water per day (by slowly weaning down the amount)?  Or, alternatively, is it possible to adjust one's chemical levels (e.g. electrolytes) to retain water longer in such a way that you do not need to take in quite as much water?</p>
