My tummy

So here's the low down I never know when I'm hungry. The only way I know I'm hungry is when I feel dizzy, pain in my stomach, or I get heart burn. I have a pretty weird acid reflects don't I. But I also can't over eat or else haha major tummy ache. My mom says its because I'm not used to eating alot, but ehh its whatever. So yeah right now my tummy hurts so I must get food. But the weird thing is my body has been demanding food a lot more then usual oh well.
