After surgery each patient may have a certain food they say "doesn't agree with me." It is important to recognize that these are usually the very foods which fill up the pouch the fastest! If a bite of chicken fills up your pouch and makes further eating impossible, often it isn't because "the chicken doesn't agree with me", but rather, because that small amount of chicken was enough to fill up your pouch! STOP eating right then and there!
To have that "second bite" is often to overeat. Your new restricted stomach can't handle it - even one more bite will distend the pouch and make you feel miserable. When you have an experience like this (most patients do) use it to learn how much of different kinds of food it takes to feel full. Try to train yourself to recognize an adequate amount of food while it is still sitting on the plate, and avoid that "painful full" feeling altogether.
This is a new concept and it will take time to adjust to it. So, go easy on this new eating pattern in the first few months until you know what that new "feeling of fullness" is like. Eating such small amounts of foods seems strange, but it is all you need to be healthy and will promote maximum weight loss.
