Getting-used-to-new-me

I'm a 56 year old male, with all the co-morbidities except diabetes, (high blood pressure, high cholesterol, atrial fibrillation, sleep apnea, arthritis in knees and hips, ruptured disc in lower back, and had a TIA about a year ago). All are being treated. I'm hoping for no meds and no CPAP, eventually. I asked my primary about bariatric surgery and he referred me immediately. I was approved by insurance a week later. I have 80 - 100 pounds to lose. My surgeon and his case manager say I'll likely have surgery before Thanksgiving 2013. My surgeon says his staff will be surprised when they see me on the table because my fat is evenly distributed. I was a body builder, (no steroids), and have lifted since I was 15 years old, and done cardio since before that. Is there anyone else out there who has a similar experience?
