Revision - waiting on approval from BCBS

So, I am definitely feeling a bit discouraged right now. I've had the gastric band since January 2011. Since the very beginning, I've had the throwing up/regurgitating. It doesn't matter what I eat. If I have any restriction at all, I'm throwing up 2-3 times per day. My current surgeon (not the one who did the surgery) also said according to the X-ray, my band is slightly higher than it should be, but not technically "out of place". They had to loosen my band, and since then (2 months ago), I've gained about 15-20lbs back. My HW 300, SW 290, LW 220, and CW 270. My surgeon said he'd do everything he can to help me. I've done the nutrition class (again) and the psych evaluation. They submitted to insurance yesterday, and she said I should hear back within 2-3 weeks if I'm approved or not.

But I've been reading A LOT of stories of people being denied for revision unless there is a serious complication with the band. I have BCBSNC. The insurance company that originally paid for my gastric band surgery was Tricare Prime, by Dr. William Richards in Mobile, Alabama.
