Connie, you've made a very difficult, very personal decision to proceed with this surgery. It's not right for everyone, but you have decided it's right for you. There are many different paths to restoring one's health, so don't let other people's judgements or beliefs about what is right for them, invalidate your choice for yourself. YOU HAVE MY FULL SUPPORT!
I hope your surgery goes smoothly and that you find yourself able to eat in a healthy, controlled way that will restore your health. Good luck!
