Hello I am four years out also. I have only put on 5 lbs since surgery but my surgeon said it was common to gain 10% back. I can tell you that I do not have the fullness feeling I once had and I have to discipline myself not to eat too much. I still only eat 1/2 sandwich, or 1/2 biscuit from Mcdonald's or 1/2 burger but its not because I dont want it. How do you eat? Dr. says this is very common! I feel my stomach rumble and roll after eating!
