Why am i never thirsty? i can go all day with one drink.

Not a good idea.: I believe u can,but U shouldn't .Is there a specific reason U avoid drinking fluids?The body loses about 2 liters of fluid a day.This is what we give patients who are n.p.o. In hospital ,to maintain adequate and normal fluid balance ( homeostasis ).I don't think you need 8 glasses of water per day , but not far from it, , is reasonable.So,drink...even if not thirsty.No pee=dehydration.
