Maybe they are following the program and eating too much and then they throw up. I love my surgery didn't have one problem. I only throw up when I don't chew my food up well and it gets stuck. But that' me that the surgery. You friend my be embellishing those stories. I have never heard 3 people from one source and a feeding tube. crazy.
Can I ask you why you decided to go with the sleeve and not the gastic or lap band?
