HI I AM a bypasser and now 2 yrs post op, don't stress follow the guide lines. When you have had just that little bit too much you will have pain or discomfort in your upper chest/ shoulder line. You will feel full up to ya chin. Just keep eating small and often and drinking in between, try and keep the walking in there cos exercise as well is the key the more you loose the 1st 6 months the better. You won't stretch ya pouch if ya follow the amounts n guide lines. Keep up with water though cos that keeps everything clean inside and promotes the healing then eating the protein helps the body to heal. It all works together. It is a worrying time when you first get home and wonder what the hell you have done, you will be fine, if you don't have sample menus look on google if you cant find any on here but I think there may be some on here or someone may suggest some, I lived on pureed fresh veg with blended meat, fresh fruit pureed, low fat custard, munch bunch snack pot yoghurts, Weetabix n stuff like that 1 tin of Heinz big soup chicken veg did me 3/4 meals. well pureed of course. Good luck xxx
