Well, whatever you do, I hope you find healing. I have never heard of having a permanent b12 deficiency. Is it something genetic?
Remember what I said about not doing too many protocols at one time. How will you know what helps and what hurts. I know your brain is giving you a hard time but you need to make it as easy as possible for yourself. Doing every protocol you can find at curezone, at the same time, to help your MS is probably not a good idea. Ask Charlie what he thinks. I don't know how well his protocol mixes with others but I would think it sure would make it hard for him to give you advise if something went wrong.
Once you start feeling better, you will love being with people and working again. It's just when you are sick that it's not as enjoyable.
