My opinion is as follows: If you trust your surgeon, and you know (s)he has what is best for your health and future at heart/mind, then do your research to help you understand WHY your doc says RNY, take time to ask any questions left unanswered by your research, and then you will probably find it easier to agree with your doc's recommendation (RNY).
I am a Bandee with Band-Issues, and my Doc also wants to revise me to an RNY. I did the research about the VSG, too, hoping I could do something "less drastic," but my surgeon strongly advises for the RNY, and after reading up on it, I understand that, for me, another restrictive-only approach doesn't meet my needs, so the RNY is the way to go. Unlike you, my Band has given me issues since Month 1. ... CONGRATULATIONS on your success so far! #125 is awesome with the Band!....and you CAN do the rest !
