Wow, I didn't know you could inject yourself.
I was getting shots at my naturopath for $30 each time, I did four or five shots, one per week I think. Not sure if it made a difference or not. He did say if you get too much it's like too much caffeine, you'll be bouncing off the walls, although some people liked a little extra.
B-12 has something to do with energy, and you need it to allow your iron levels to be restored.
I'm sure someone more informed will weigh in here...
