Hi Docsdeb, I am pretty much a newbie myself to the band-my surgery was 3 weeks tomorrow. Unlike you (and other smart people), I didn't start reading posts on this site until after I'd had the surgery (of course I did research on websites but just not on message boards). Maybe it wasn't such a bad idea after all because I didn't have the same opportunity as you to have all the pre-surgery doubts you are having, although I did have some, certainly!
Naturally some of the posts I have read have caused me concern but I think we have to remember that often we're reading posts from different people who have had different issues. One can only hope that all of the various problems don't happen to a single person. I'm fairly certain that there are many, many people who have no 'issues' at all (other than the expected 'breaking-in' period for the band and the learning curve about eating with it). As we all know, there are risks in life and we have to weigh them against each other. In my case it was, do I live in misery with my excess weight-constantly being tired and unmotivated to move or do anything much but go to work/come home/eat (lots of course)/sleep repeat. While I didn't have any serious health issues (amazingly), they were just around the corner. Comparing those things to something that had a comparable long term rate of success similar to the more invasive surgeries but far less percentage of serious complications and could be reversed in the worst case scenario, I chose the band. Time will tell whether it turns out to have been a great choice, but I'm hopeful.
Bottom line is you have to feel comfortable yourself with this choice or it will truly be nothing but a stressful weight (no pun intended) around your neck if you proceed. I wish you much luck in your deliberations!
p.s., I have sleep apnea and my clinic said that while complications with anesthesia are very rare, they did want me to stay overnight (at an extra cost, of course) so they could just make sure all was well.
