I weight 200lbs and I'm 5'4. I drink 132oz. of water a day, everday. Mostly because I feel so dyhdrated from constant D, also because of the diet plan I follow. Honestly though for your size, you seem to be drinking a LOT of water, perhaps a dangerous amount. I'm not a doctor though but I seriously suggest if you are THAT thirsty to find out what is actually going on inside your body.
