Hi Plain, I usually eat until I'm full and try to stop before I'm over-full. So portion sizes are my problems. I usually eat double portions (guessing) before I really feel satisified. But, I'm getting a fill tomorrow and hoping that will help. My doctor takes it real slow and in the past when I get a fill my tummy and band disagree for about a week. After that it goes pretty good. Each time I can tell I can eat less and less at each meal. I'm in my fifties and my activies aren't too good either, plus I have a desk job so not much burning calories there.
