Mrs. D and Stacy thank you. Wow Stacy now I feel normal after your levels. Ladies can I ask do either of you know just out of curiosity, how long after stopping b12 would blood levels decrease to the "in range" levels? Weeks, months?

If my pain creeps back in I'll use b12 quicker then a kid in a candy shop! I wanted to mention not sure if this is useful to any of you but I was using a methyl product that was free of flavors, colorings in a nasal spray. I think it is safe to say it works to raise levels.
