YOu will definitely know when you have it. I was lucky and got to mine on my second fill (5 cc) in a 10 cc band. I am still working on learning to eat very slow and take tiny bites. I was on a role loosing but have slowed down. I am wondering if it was because I was not eating enough calories. This weekend included quite a bit more calories, but I am too scared to get on the scale, so I will wait until Friday to see if I maintained, gained, or lost...
Good Luck!
