Hi Rose, I checked my Time Line and saw that on 8/2/99 I noted that my fingernails were no longer as blue underneath. That was 8 months after I was shown how to give myself the shots. I can't remember if that was after my neurologist told me to have more shots... I read it, but I can't remember. I'm too tired to go back and read it again.

I still had my period for years after that... (which my Time Line also shows)

So, I think B12 makes the blood cells able to carry iron better, or something, because of the way it allows blood cells to divide properly.
