I lost 15 lbs on the pre-op diet and have lost an additional 8 lbs since the surgery. I'm pleased with the progress so far, but am afraid of the comments I read here about folks who take a long time to see results. I won't have my first adjustment for a few weeks! Will I gain some back when I get to the next stage of eating? Also I can see the weight loss everywhere except my stomach? It is still bloated and swollen. I walk everyday and take Gas x, and that nagging left shoulder pain is driving me nuts. When will the swelling and gas go away?
