hmmmmm.... my friend had this problem once. are you constanatly thirsty??

actually yes which is why i drink gallons of water everyday

and constanly tired?

yes ma'am in fact when i finally did get to sleep last night i woke up half an hour later and downed a liter of water.

yeah this sounds a lot like what she had. have you been tested for diabetes? this is what hers was. maybe it's that or something closely related.
