I am having trouble with upset stomach. It seems everytime I eat anything, no matter how much or little, my stomach gets very upset. I have taken Maalox, Rolaids, etc. and they really are of no help. Another thing is that even when I eat a large meal and know that I have to be full my stomach still has what feels like hunger pains. So what ends up happening is that I feel sick from feeling like I've eaten too much, yet my stomach is still sending out the hunger pain signals. Have any of you had this kind of problem? Is it related to FMS?
