Pedialyte power

I was cleaning out some old newspapers and found an interesting story on hydration in the Style Section of the Sunday Sept. 9 New York Times. It's on Pedialyte, a drink for infants with diarrhea that some people use to combat dehyradation when working out and running long distances.
I first heard of Pedialyte when reading Dean Karnazes' book Ultramarathon man. I've never really sought it out though because it's supposed to taste so bad. Apparently it also costs tremendously more than Gatorade.
