I had my first fill at the OCC 6 weeks after surgery. I felt restriction maybe for one week. I went to Fill Center USA 5 weeks after my first fill, and was given a helluva fill. Nearly double of what I was given on my first.
I have no idea how it works. I appreciate the OCC being cautious with my first fill. I wouldn't have wanted to return home and ended up in the E.R. getting an emergency unfill with a cost to me of about $5,000!
I do know that as you lose weight, you might need additional fills. And also heard that the VG band might require more fills than the smaller band. The more weight you have the lose, there's a possiblity you'll need more fills than somone who has only 40 lbs. to lose.
I'm a firm believer that the lap band works in the background. You'll hear many of us (I'm guilty too) say we have no restriction and that we're losing weight because of what we're doing, not because of the band. The band's just not slapping us in the face all the time. It is working but we have to work with it.
