Don't worry. Eat slowly so that your stomach has time to tell your brain that you are full. When you feel full or a tightness in your back or chest, stop eating. It is unlikely that you will strech out your pouch at this point. Your pouch will sdjust after time and allow you to eat more. You may even notice a few days after your fill you will be able to eat more. I was eating about 8 oz before my first fill (ap band) and I actually called my doc and asked if I could come in earlier for a fill. He said yes and I got my first fill at 3 1/2 weeks. Right after my fill I ate about 4 0z. About four days later I was able to eat about 7 oz. Your pouch will adjust a little, some more than others. I try to just stay active and eat really slowly, and chew well. It will work!!!!!!!!
