As an aside.

If the interest is in quickly treating dehydration, I think plain water is preferable to a drink with ORS.
Referencing Cody Lundin's "When all Hell Breaks Loose"..

Plain water passes much more quickly to the large intestine where it is absorbed by the body. Water mixed with ORS causes the stomach to treat it as food, delaying the liquid from reaching the large intestine and rehydrating the body.

After I complete a vigorous MMA training session in our relatively warm DOJO, I find drinking water to help much better than a commercial ORS. I believe another poster indicated the same.
