Is it normal to drink a gallon of water a day?
SO here is the deal.
I am 19 years old, average built about 125 lbs. I work out but not intense, just cardio for 30 min, 3 times a week. But i am constantly thirsty! I end up drinking a whole gallon of pure water a day (i even carry a gallon because i cant refill a nalgene water bottle that fast)!
I went to the doctor but even she cant figure out what is causing me to be so thirsty all the time.
Has anyone heard of this or know what can be wrong?
Please help with comments!
