I have completed all of my pre-op appointments, Nutrition, Psych, Cardiologist. I didn't have to have a sleep study because I already know I have sleep apnea. I have to give my primary Dr consent letter to my surgeon and then they can submit for approval to the insurance. I have no idea how long it is going to take them unfortunately. I may know more on Friday, I am going to the surgeons office to speak with the on staff nutritionist because they want me to lose weight before surgery.
