I think something must be wrong with the salt intake in my diet. I've been drinking plenty of water everyday and no matter what I'm still thirsty. It seems like I piss the water out as fast as I drink it as well. As far as I know you need more salt to retain water. I eat fairly clean foods but I would think that I get enough salt in a day. As far as caffiene goes (it's a diuretic right?), I only drink 1 or 2 cups of green tea a day, no coffee and no pepsi. Any suggestions? EDIT: I know that it is not diabetes or something like that. I had a blood test done about 6 months ago.
