I completely agree with flutterby, weight loss with the band is definitely a mental process. I found in the first few months of having my band I was more interested in the restriction and thought that was the only path to losing, but after getting advice from this forum and then seeing a private Dr for a fill, that restriction is really only about 25% of the process.
I think my biggest hurdle in the beginning was eating until I felt full and maybe to some extent overeating because I didn't have restriction. I changed that style of eating and now I eat smaller portions which keep me satisfied. And who knew drinking water as a wieght loss tool worked.
I recently had 4ml taking out of my band so technically was able to eat everything. But I have managed to continue eating like my band is at full restriction.
Try not to wait for the ultimate restriction. Also i noticed that it took at least three to four weeks for restriction to take effect whenever i had fills done. Start changing your eating now, Try to serve yourself less food. Good luck and don't get disheartened.
