Hi Freddd, Thanks so much for your reply, I really appreciate it. I had a bit more of a look around this forum and found your mB12 protocol. Very interesting. I read quite a few pages and now my head is spinning! I think that I should give it a go, though I'm so confused as to what to try and what not to at the moment. For some reason I seem to have crashed again recently, even though I've been doing very little. I was planning to follow a treatment plan outlined by Jonathan Campbell (http://www.cqs.com/immunedisorders.pdf) and have ordered a bunch of things from iherb, but now I'm thinking that maybe I should do the B12 thing. Terribly confused. - And sorry if this is the wrong place to post.
