Congrats on the decision to do the surgery. I told friends about it, but not family. They were the ones who were so nasty with their comments when I was at my heaviest. Some people do act like we took the easy way out, not realizing this isn't easy at all. It is a whole lifestyle change. I went from being a couch potato to walking three miles a day and working out at the gym three times a week. The whole lack of eating is an adjustment, too. I would kill for a steak sandwich, but after one bite would regret it. You don't need to be nervous, tho it is hard not to be. The results make it all worth it. Good luck
