As someone who is dealing with a very thirsty "pre-diabetic" chemo patient...he has been drinking Powerade instead of Gatorade because it has less sugar. Popsicles, and italian ices help with the thirst also. In the cancer center where he gets his treatments, they have canisters of lemon candies available for the patients. The tartness stimulates the production of saliva and he has a pocket full to suck on during his treatment. Of course, I keep bottled water by the case. He likes it in the freezer for a half hour or so to be icy cold. Says the coldness helps with the thirst as well.
