Hi I just had my sleeve on Wednesday and taking the protein shakes and drinking lots of fluid. Not sure how much I have lost but maybe you are putting in more calories than normal. Everything will pay off just look into foods that you can eat but of course portion control Is the key. As for me I am just in the liquid diet right now and been feeling full with only the protein shakes, and chicken soup that my mom has been making me. Good luck!! And you should be happy with what you have lost!!
