LilliB: You have some work to do with the deficiencies. When I found low D I was at about 16 as I recall and when I finally got to 80 I felt great, then had a hip replacement and D dropped which I read could happen with surgery, so I've been working my way up and now around 50something, I skip some days with D but will take some right now as talking about it. My low D was found when I about 68, I spent a lot of my life in the sun for years, then got out of the sun and Poof.....

Hope you begin to feel better.
