I think you need to figure out where those negative posts are coming from, and put everything into proper perspective. In my experience, those people who are the most educated about the band and how it works are the ones who have the fewest problems (if any.) They're not making a lot of posts anywhere because they don't need to ask for help, or complain about what's working for them. The negative posts you're reading are from a relatively small number of people, when compared to the huge numbers of people who have the surgery every year. If someone isn't having an issue, why post about it anywhere?
One reason I chose the band was that it's reversible, and I can get my system mostly back to normal if I ever need to have the band removed. But at this point in time, after nine months of consistent and (frankly) remarkable weight loss, I have no intentions of going back, unless I should develop some sort of issue with the band at some point. If it ever happens, I'll make the right decision at that time. In the meantime, I'll keep working my band like the tool that it is, and I'll continue to enjoy living my life as the skinny person I always knew was living inside of me. Put me down as someone who has nothing but good things to say about my band experience.
Good luck in your journey!
