My wife is the same. I was banded in 2007, and it slipped within the first few days. As a result, my weight loss has not been good. I was able to eat pretty much anything.
She thinks the sleeve will fail, too, or I will at least eat around it. She doesn't want me going through another surgery, either. She thinks it's too radical and risky since I'm "only" 235 and 5'9". Our out of pocket share of insurance is already covered for the year since we had a baby and I had my gallbladder out, so the surgery would basically be free as long as I have it this year. She also thinks I can just lose enough of the weight myself without surgery.
She's basically not supportive, and thinks I shouldn't do it. It's very discouraging, to the point that I don't talk to her about it.
She may go to the seminar Monday night with me. We'll see how that goes.
Thanks for letting me vent.
