My initial dose was 20mg starting 12/23, I was down to 10 mg on 6/24. I can't promise you that I was splitting my dose in 1/2 morning and night because I was not recording my dosing. I did starting waking up at 2 or 3 AM feeling wide awake so I tried backing off on my night time dose with limited success. There was a time this Janauary where I did need any pred during day and was only taking it at bedtime. My approach has been to adjust my dose based on how I feel Rheumy's don't like that either. I've been as low as 1 mg/day and felt ok. Right now I have a shoulder that is giving me some issues, might be something other than PMR it's really hard to know. Hope this helps and best of luck!
