Thanks for the input, everyone. I was approved by Dr. Aceves so I may well end up going to Mexico to be sleeved in March. I will make up my mind after I meet with my local surgeon next Friday.
Rene, I'm like you -- I can lose the weight if I make a career out of it, but I've never been able to keep it off and I'm afraid I'll just get bigger and bigger over time without the surgery.
The very few people I've told think I'm out of my mind, but I am feeling confident this is going to be a great choice for me.
