I'm new and just had the sleeve done, and I am very happy so far. between my 2 week pre op diet and now. I have lost 31 pounds. I drink Premier Protein shakes twice a day with a creamy soup for lunch, and drinkable yogurt for snacks. I am not tire, or hungry, and best of all no cravings. I do admit when my hubby fixes dinner for him and my daughter it smells good, but I don't hunger for it. I have no had any bad side effect, Thank God! Next week I start on soft foods, and wonder, is it when you start back to eating regular food when you start having problems? Or did some of you have it right away?
