After posting my question, I found yours. I know how you feel. The only thing different is that I feel empty. When I am not full I feel nauseous and my stomach feels so upset. I just wanted to let you know that you are not the only one feeling this way. When I was searching the web I came across some sites that pointed to all sorts of disorders, most I cannot even say. Sorry I cannot help, but I am searching for the answer just like you!
