I love the band, personally. There are not as many LONG TERM complications, IMHO... I don't want to be attached to supplements the rest of my life.
The band also offers me exactly what I want. I wanted HELP losing weight. I did not want a surgery to do it for me. I knew in my heart that I am strong willed, motivated, young, love myself and am willing to do what it takes. But I also had PCOS and 150lbs to lose fighting me. I knew I couldn't do it without help. I got help on May 13th. I am now down 42lbs.
If you have faith in yourself that you can stick to the rules (which, with the band, are significantly easier to do than doing it without any help) then you will do AMAZINGLY at the band. No worries. My doctor is one of the top in the state...named by a Top Doctors yearly list. He believes that the band is a fantastic tool (though he does more RNYs) and believes that if you need help and can follow the rules, there is no reason you can't succeed....and succeed enormously!
Think about what you want from a surgery. That helped me make my decision. Now I feel great that without malabsorption, I have already lost so much weight. It is so FRICKIN empowering!!
Good luck!
