I was banded the same day as you. I am feeling everything you are describing. It would probably take least a cup of food to get that sensation, but I stick to the 3-4 oz. my doctor recommended. I am hungry again in an hour. I have an 8cc band with a 2cc fill two weeks ago. The doctor had intended to put in 4cc, but I got stuck at 3cc. I will go back in another week to try another fill. I was beginning to think my band had slipped or I had stretched my pouch. I have suddenly gained 2 pounds. However, I just had my first PB and believe me, it is an experience I do not wish to repeat, so I guess this band is working. Maybe additonal fills will help us.
