Tricia,
I don't know how they are rehydrating you, but I am glad that it has worked.
Believe me when I say that Gatorade is much tastier than Pedialite (...which was no fun to experience - though it worked very well).
I suggest that you carry a few bottles of Pedialite in your car and at home at all times. It works, quickly.
On a side note, I still wonder why we "experienced" desert dwellers/workers dehydrate ourselves so often. It is just another mystery to resolve.
RO - thank you for the updates. They are appreciated greatly.
