My preauthorization went through fairly quick. I attended a seminar on 5/21/13 and was approved to move forwards on 6/29th. Dr told me to lose about 15 pounds...I called on 7/10 to report that I'd lost 17 pounds. He wanted to set the surgery originally for 7/20, but he was booked that day, so I am scheduled on the 2 to making the biggest decision in my adult life! To change...for me! Good Luck to everyone out there!
