Thank you Mrs. D. Yes, you did mention the other B12's above and I appreciate that information. But, more specifically I am wanting to know if those other B12's are likely to give me similar symptoms as the methyl version? I am a little hesitant to try anything other than cyano now for fear of the severe negative symptoms.

I have read the Pfeiffer and Walsh material and the over-methylation sounds a lot like me.I still need to get tested though. It is my understanding that if one is an OV that they need to avoid methylated supplements; do you agree with this?

Thank you for your time and patience as this is new territory for me.
