I was banded in 2011, and I wish I wasn't. Sure there are lots of folks with success stories, but there are many more stories of how the band just didn't live up to the hype, in fact 2 of the major manufactures, aren't making parts any more and LOTS of surgeons aren't performing installations because of the high failure rates, low success rates and lack of manufacturer support.
A about 6 years dealing with trying to get the band to work for me, all the depression and issues because it didn't. Getting stuck on foods I shouldn't, etc etc etc. I did lose about 70 lbs, but that was it. Nothing else I did would make that number move any farther. I started to rebound as well a few times.
When I finally had the band removed and revised to the bypass, my band was 100% completely encapsulated in scar tissue and took my surgeon over 3 times longer to remove than it should have, I had no "issues" though... no slippage, no erosion, yet, the band was screwed up, no idea what would have happened if I just left it and continued to deal with all the problems.
Congrats on deciding to take the first step on your WLS journey, I would however strongly caution away from the band.
