Stuck food result in band open

I have had my band for 2 1/2 years and had lost 85 pounds and felt really great. Then I began to throw up alot and found out that my band had slipped. My doc took care of that. I had been going for fills and was at the max and gaining weight. I had an espophogram and was told that my stomach pouch is enlarged. The doc took out some fill and told me to sit tight for a month-that the stomach would reduce in size. I went back to him after the month was over and he added a bit of fill. I feel very little restriction and,because I am not watching what I am eating, have gained alot of weight. Has anyone heard of this happening and can it be fixed? I have to call my doctor on Monday....I don't want this to happen and am really very upset.
