I've been waiting to update my progress until I got my DXA scan results which finally I did this morning. Happily there has been a noticeable improvement and they are no longer recommending OP drugs, nor will I need another scan for three to five years! So nutrition and exercise do work, even when on low dose long term steroid treatment!
As for the low intensity light therapy (I refer you to my previous posts on this subject available by checking my profile) although it's taken me three months to reduce .5 mg to 2.5 I believe that yet again the LLLT has helped. I tried reducing (always using DSNS method) and found near the end of the taper that I was getting shoulder pain, first time since starting pred last year. So went back to my comfortable dose again, called the physiotherapist and arranged to increase my visits again. I had been going once a fortnight for a few months, so we increased to once a week. I tried the taper again, and this time, in spite of a few days where I wondered if it would "take" I appear to have been successful. It's good to be at 2.5. 
Worries about the drop but under orders for scan
