I have tapered to .5 mg of prednisone after being on it for more than 4 years since my PMR diagnosis. Starting Actemra 6 months ago had allowed this and has basically put me into remission. I am pretty much pain free, but exhaustion remains a huge problem. I sleep 10+ hours per day and still feel exhausted. My rheumatologist and I have discussed this and wonder if it might be due to long Covid which I have experienced since I was infected in July 2021. I lost my sense of smell then also that I have never recovered. I understand how debilitating exhaustion is. My heart goes out to you.
