Stef,
I had similar problems. After my first fill I was still able to eat everything in sight. I was concerned but just went with it. During my second fill the Doctor noticed that I lost 3 cc's, and thought maybe this was something wrong with the port. At my third fill again I lost saline. They felt I may have a leak in my port and scheduled my for a quick out patient procedure to change my port. When the doctor opened me up he couldn't find any leaks in the port and decided to replace the whole band. Since then I definetly feel the difference. I don't feel hungry all time, but I still have to be careful of old habits that can easily get past my band, such as cake, muffins, etc... I'm losing about 5 lbs a week since the "fix". Stick with it.
