I had my a band done in June of 2019, the only weight I lost was when I had to prep before the surgery and restrictions after the surgery total weight loss was 33 lbs, up to date I gained back 22 lbs and that after so many tights. I east the same portions I ate before, never threw up from overeating, can drink right before during and after the meal. I am not sure if my band surgery was successful. My doctor says I have to diet. So why did I have a surgery then? Does anyone have the same issues?
