I wondered where you had disappeared to! It seems you have succumbed to what (I believe) will befall many bandits, and that's the failure of, or problems with, the band. Sorry to hear you have had a rough trot, but from all I read and research it looks like the sleeve is a MUCH better long-term option. I honestly never thought I would say that, but then not many of us thought we would have issues with the band, especially when it was marketed so skilfully, the downside never mentioned.
I wish you all the best with your surgery, and hope that the outcome is much more favourable than what you have experienced to date.
Take care. Would love to hear from you post-surgery when things have settled a bit.
