David, if you have every bit of confidence in your doctors, then things will go more smoothly for you. Think happy thoughts on the day of your surgery like, PT, Thursdays, your sweetheart, Mario, ya know stuff like that. Before I went into for surgery, I was laying on a beach, under a palm tree, drinking Pina Colada's. Next thing I knew, I was in la-la land feeling relaxed.

Wishing you a full and speedy recovery.
Prayers and positive thoughts heading out your way.
