Good luck ... I think you should go for it. The follow-up labs and visits sound reasonable.
Don't expect any sudden changes. It takes a while for Kevzara to be eliminated from the body so if your symptoms return it should only be gradual.
"Kevzara Half-Life & Duration
Half-Life: The terminal half-life is concentration-dependent, measured at approximately 8 days for the 150 mg dose and 10 days for the 200 mg dose at steady state. Some sources indicate a longer, average elimination half-life of 21 days at steady state.
Time to Clear the Body: Following the last steady-state dose, it takes roughly 28 days (for 150 mg) to 43 days (for 200 mg) for the drug to reach nondetectable levels."

I have experience with stopping Actemra but not in a very controlled way. Actemra was "interrupted" once during Covid because of a shortage. It was 6 months before supplies improved. I had to go back on Prednisone again after about 3 months from my last injection of Actemra. My symptoms weren't that bad but my inflammation markers were increasing.
My other experience was more of a "trial" just to see how long I could go without an injection. I gradually stretched it to almost 4 weeks but I couldn't stand the increasing lower back pain.
A synovial cyst formed on my lumbar spine so surgery was being planned. I needed to be off Actemra for a month before surgery and a month after surgery but that wasn't going to happen with Actemra injections.
The idea was to switch to a monthly infusion of Actemra with the hope I could go 2 months between infusions with surgery in the middle. After Actemra infusions were started the synovial cyst on my lumbar spine was reabsorbed. It could have been a coincidence but it is rare for a lumbar synovial cyst to be spontaneously reabsorbed. In any case, surgery was postponed.

---------------------------
The surgeon said the synovial cyst might recur so the surgeon was still recommending surgery to stabilize my lumbar spine. I advocated for myself and refused surgery because the pain was gone. The agreement I made with the spine surgeon was that I would call when I was ready for surgery. That agreement was made almost 4 years ago and I'm still not ready. I'm more inclined to stay on the Actemra infusions because it seems to have some additional benefits besides treating PMR.
