I'm the opposite - I can go a day or two w/o drinking anything at all. Usually the only time I drink anything is to wash food down! I was sick and couldn't eat or drink for 4 days and still didn't get dehydrated. Very few times have I ever been "thirsty". I'll walk on the treadmill for an hour, sweat like a pig and not be thirsty. My Dad is like you - always drinking water and I think I freak him out
