@potterywoman I too have a window just about every day that appears somewhere between 3 pm and 7 pm almost daily. That is usually my best time of day to plan for any activity. ( housework, meal prep, shopping, walking etc.). Have no idea why as I have always been a morning person. Pain and stiffness too great now in AM to get moving quickly.

@potterywoman My understanding is that the pro-inflammatory cytokine (?) levels, which rise in the morning, often dissipate as the day goes on .

I'm experiencing this phenomenon as I write, in fact. I'm currently at 10 mg, trying to establish my Lowest Effective Dose. 10 mg has been a rollercoaster: some days zero stiffness/achiness, some days all over symptoms. Today, I took my pred at 3:45 AM, and had zero symptoms--until about noon, when the unmistakable upper-arm PMR aches set in. At 4 PMish, it started to go away again, and is now pretty much gone again.
