I don't have many fat friends either. I did decide to tell them I was doing this (I had surgery last week 5/7/10.) I am getting a lot of support but my secret fear is, "What if I screw this up and I don't make it work?" What will I say then? I know I will have to educate many of them about this - it is not as rapid as bypass, there are plateaus, etc. I guess it is about balancing expectations of yourself and everyone else in your life. I know I have to trust my path and that my true friends will continue to stand by me.
