I did all the research, made my decision, got the surgery financed, set the date and then stopped thinking about it. I kept myself as busy as possible and just focused on the Dr. ordered diet. I tried to diet as though I wasn't getting the band and lost 40 lbs.
From what I've read on this and other sites, it seems like some people really dwell on it and it doesn't seem to be very helpful. Educate yourself, make your decision, set up the arrangements with Dr/insurance/financing and then don't obsess!
I had a smooth surgery, no anxiety and quick, painless recovery. Just like our overeating, I think that all aspects of this process are greatly effected by our emotional and mental state.
Good Luck!
