Everyone is different. I've read that you have to find your "Sweet Spot". I have a Realize Band and am at 6 1/2 cc after 4 months. Last month only lost 2 lbs and was hungery every 3-4 hours, so I had a 1cc fill. Now I have a lot of restriction and am not hungry in between meals. I've been told to eat only 3-4 oz of food each meal, 3 meals a day; eat protein first, vegies last. I believe I'm at that "Sweet Spot". It takes time & patience to know what amount is right for you. Good Luck!
