Reconcowboy:

I recall reading on one of the "military style survivalist" sites that the body can only process a certain amount of water intake per day and even if you continue to drink, you can become dehydrated from loss of water, with the only solution being rest to reduce the amount of water lost since anything the body can not process per day won't help.. They also suggested salt in order to retain the water in the body.

Some of our more knowledge medically oriented forum members may know of this physical limitation and they can better describe the quantities and conditions that arise.
