Hi Christine,
I'd say don't be nervous but, heck, I was nervous. Of course it was all for nothing (except I burned a few more calories) because my surgery went fine. I always say the week before surgery was harder than the week after. Nerves can do that to you. Keep it postive. That means only positive people around you. The negative ones are just ill-informed. I hope all your health and weight-loss dreams come true. All the best,
