Going back to the GP next week, feel full nearly all the time even when I'm due for a meal, this has been going on for years, she doesn't seem that concerned because my weight in constant, she just gives me the same old advice to eat 3 meals a day, have told her so many times that it's hard when you don't feel hungry and I also don't know how much to eat, I'm also burping constantly, I do have a gall stone but it stays in the gall bladder because it's too big to come out, could that be the problem? Any one else experienced this
