Wishing you the best in 2023 @connelly and hoping you get some relief. My first time with PMR took 3 and half years to taper off without the morning pain. I still have the stiffness in the morning until I start moving around but that's pretty normal for my age.

Have you made any lifestyle changes to see if it might help with your tapering and pain? Some good information here if you haven't already tried them.
