Until recently, I had been on Metformin (4 pills a day) for about 10 years and Avandia (4 mg a day) for about 5 years, both common drugs for diabetes.
I am proud to report that I have been off all diabetes medications for the last month (I had been slowly reducing dosages) and my blood sugar has tested normal the entire time. I looked at the study, that was entirely comprised of "lower BMI - between 30 and 40" and as you can see, I started at a significantly higher BMI. The proof is in the pudding (or in this case - the cottage cheese)
Hopefully the insurance and medical establishments will see more of the long term health benefits and make getting the surgery easier!
