You started on a high dose for someone with PMR! I started at 60 to treat GCA and PMR. I've been taking Actemra for a year and a half, and I finished prednisone 6 months ago. My worst side effect from the prednisone was insomnia, and that diminished a lot at 40 mg. I had a problem with muscle strains when I was exercising as I tapered from 20 down to 10, and then that problem went away. I started losing the weight I had gained and my moon face as I got below 7. I only had a ravenous appetite in the first few weeks I started treatment, at 60 mg. The rest of the time I had a sluggish metabolism, and it was hard to know what and how much to eat. My metabolism only recovered about a month after I stopped prednisone. I had elevated cholesterol until I got down to about 15, and then that cleared up.
