Off prednisone since mid-September, slow taper for 18 months, PMR still in remission, but the fatigue and endurance has suffered since the taper reached 7mg. I can be physically active and mentally sharp until about noontime, then it is all down hill for the rest of the day. Having PMR has aged me considerably in the last two years. Cortisol test came back above normal, so Adrenals are working. Seeing an endocrinologist in January. Maybe this is 'normal' for a 76-year-old but I don't like it.
