I seem to be very susceptible to dehydration. Prior to any rescue, I drink plenty of water, but seen to sweat it out within 20-30 minutes. While I carry both water and either GATORADE or what I like better SQUINCHER, it is sometimes difficult during the operation to stop and rehydrate thoroughly. With this in mind, we keep a close watch on each other and make sure that if we notice anyone starting to show signs of dehydration and it is feasible, they stop, take a break and rehydrate. For me personally, I get a very weak feeling when I am dehydrated and find the extra caloric boost from SQUINCHER to be helpful. Pete
