It took me 3 and half years to get off of prednisone the first time my PMR was active. The second time I made some changes in my eating habits and exercise which helped me get off of prednisone a lot quicker the second time around. Have you looked into any lifestyle changes to help manage the PMR symptoms and tapering?
