I'm trying a modified version of that slow reduction. After having pain increase on the 8mg reduction, I moved back to 9mg and have stayed on 9mg for a few weeks to stabilise the improvement. All good now, just minimal pain in the mornings.

My doctor has agreed with whatever slow and steady taper works for me, so I've started reduction again a few days ago.
My dose was 7mg morning + 2mg evening = 9mg

Reduction schedule:
Day 1 - 6.5mg morning + 2mg evening
Day 2 - 7mg morning + 2mg evening
Day 3 - 6.5mg morning + 2mg evening (dose I have taken today)
Day 4 - 7mg morning + 2mg evening
Day 5 - 6.5mg morning + 2mg evening
Day 6 - 6.5mg morning + 2mg evening
Day 7 - 7mg morning + 2mg evening
Day 8 onwards - 6.5mg morning + 2mg evening = 8.5mg new dose.

The plan is to sit on the 8.5mg for a couple of weeks to make sure pain is still minimal before reducing by another .5mg in the same way. Hopefully, an overall reduction of 1mg will be made within the guidelines of reducing by 1mg every 4 - 8 weeks, so it's not really going slower, just more carefully and gradually.
