tizzylish My co-morbidities were, high blood pressure, diabetes, sleep apnea, hypo-thyroid, bad back & knees. I have lost 82 pounds, I now take less medication. Exericse for the bad knees & back try water aerobics. I know you don't want to be in a swim suit in public but it does burn a lot of calories and is easy on the knees and back. There used to be a thread on this site that list the insurance companies and stories of people & the problems and successes of getting approved. Hang in there.
