I have 8.25 cc's in a 14cc band i had surgery on 7/11/11. my Dr. told me after surgery that I probably wouldn't get to my sweet spot until i got about 10cc's, but i am down 32lbs since surgery,44lbs total so i'm ok with that, it may take you getting half way full, before it work,but that' s ok AS long as it works. As long as you are not gaining,,,is even better
