The vitamin D thing seems to be the new piece of knowledge of the day for me. I got an email from a close friend about it two days ago--same thing, severe deficiency, prescribed the once-a-week megadose. Saw my rheumatologist today and she raised it and we had blood drawn to test it. There's a great Johns Hopkins article about its role in arthritis and pain. I had no idea till I got that email two days ago.

And, PS, I got an alarm clock for my other close friend back east that does the dawn simulator thing and she says it's a huge help. She's an ICU nurse that does 12 hour shifts, and has to get up at 5:30 am--hard in those NY winters.
