This is my first bout with PMR, started this past summer on 15 mg prednisone , so I can only share my positive experience. I immediately went on a strict anti inflammatory diet, no alcohol, no dessert or added sugar, no processed foods. It was a bit difficult but I have never been hungry, I eat 5 times per day. I do at least some exercise every day, even just walking. I’ve lost approximately 25 pounds without really trying. I think because of this, so far I’ve minimized most of the poor possible side effects from prednisone and have had success in tapering my dose 1 mg every 2 weeks with rheumatologist advice. I haven’t gotten moon face so far, blood pressure is lower than before pmr, cholesterol and other lipid profile better than before pmr. Main stubborn side effect has been high A1c. In summary I think it’s helped tremendously and believe even if it doesn’t directly reduce your symptoms, it helps your overall health immensely. Anyway best of luck on the journey.
