I thought I'd post my experience as the fill topic seems to keep coming up in different threads.
I was told at the OCC that 3-4 fills in a lifetime was the norm. Of course, I thought I'd beat the norm and that I'd have perfect restriction after surgery. Not a chance.
After the swelling went down, there was no restriction at all. My surgery-day weight was 201. I dropped down to about 195 prior to my first fill. When I got my first fill, I was given 5 cc - which I thought was fabulous. But again, once the swelling went down, there really wasn't much restriction. I did manage to lose another pound or two before my next fill.
At this point, I decided to stay local and went to a doctor a few cities over. He didn't use barium, but did have me drink water during the fill to see how it felt going down. I was given another 3 ccs during this fill. This fill allowed me to experience restriction but it only lasted about a month. When I realized that I could eat large / regular-sized / pre-band meals, I decided to go in and get another fill.
So I went back in and the doctor added another cc. This was good, but only for a few days. Luckily, my doctor will allow you to come back in within 2 weeks to add more or take some out if the fill isn't just right. So I decided to take advantage of it and went back in for another cc. I did the water test and thought it was fine. This brought me up to 10 cc. When I got out in the parking lot, I tried drinking water in my car and I started sliming - this was the first time I actually experienced that, even though I thought I knew all about being stuck, PB-ing, etc. I wanted to keep the fill, knowing that each fill that I've had has loosened up within about a week. But, I knew better. I went back to my doctor later that hour and they took out about .3 cc.
The restriction was great, and lasted for a month. I considered going back in and getting another fill at this point, but right now, I think I am losing at a nice pace. I am actually losing steadily now - at least so far. I figure that if I'm still loosing, there is no need to get another fill.
I also noticed that because of my aggressive restriction-chase, I had grown accustomed to being pretty tight and was babying my band quite a bit, relying on sliders and protein drinks. Now that I'm following the rules (protein first!), things seem to be easier. I'm not hungry in between meals and am not feeling ravenous during meal times. I am able to eat larger portions in the evening, but that doesn't mean I do. I can feel quite satisfied with smaller amounts.
So, hopefully I can get a bit more mileage out of this fill.
. . . and hopefully this post will help someone.
