I just had my sleeve done. I was wondering many of the same things with regard to new technology. I found quite a few cool devices that are being tested but it will be years before they would go to the market, if at all. I still feel the VSG is a rather safe way and really a brilliant concept. It's just a tool, though. We still have to have some healing in our brains... takes more than just the surgery, I think, to make us function better than before. I have a therapist lined up and plan to attend groups when I'm healed.
You sound like an analyzer like me! I know after reading and researching, that the sleeve was what I needed.... even though it was a scary decision.
