To ru218, The doctor started me on l inj. of cyanoB12 (that I'm still on) lx a week, 1cc. I was on that schedule for almost a year. These doctors!!! I didn't know that much back then. I've only recently gotten on line to do research, and am learning a lot. I am working on getting my neuro doctor up to speed too. He's been great. My injections are only lx a month now. I also do sublinguals. I've looked around this area, and nobody sells the MethylB12 in any form. Neuro doc. should agree to those injections and I can get sublinguals on line. Thanks for the nice words. I appreciate it.
