Hmmm... that's interesting. I used to get bad pins and needles all the time - one time, I woke up and my arm was so numb, I couldn't move it for several minutes! Another time, my fingers went numb and it was the middle of the day before the feeling returned.

This hasn't happened to me in a long time. Last fall, I started eating a lot more Yves veggie burgers and other Yves products, and they're all loaded with B12. On fitday, my B12 intake is usually 200-500% of the RDA. Coincidence? Maybe that was my problem.
