I lost most of my weight before my first fill. Since my first fill in March 2007 (1 year) I have lost 25 lbs. I definately feel the restriction, and listen to it when its there, and can feel the difference when it leaves. I am currently on an appetite surpressant as well as definately feel the difference. My Dr. feels if it were habit, I would have no diff on the drug or off.
I was tracking my meals for a while, and know when it is me being "bad" but this is definately not that.
I don't have a leak (at least a measurable one)
