I have been constantly tired no matter what I do or how much sleep i get, I am always thirsty (I have to carry a cup around with me wherever I go and don't use the restroom more than usual,) I also have a burning sensation in my stomach quite frequently and chest pains similar to that of intense heart burn. In addition here lately, I have an awfully hard time staying asleep. i can get to sleep just fine but staying asleep is just so difficult, I wake up approximately every 15-20 minutes. What is wrong with me!? My bf thinks i'm just being crazy drinking so much and tired so often he's getting irritated!
