Well, thank you Mrs D, that's a really helpful response! I am an allergic to proteins in wheat in particular and to gluten (not officially coeliakie, but an integral doctor found I was allergic to this). I also have a cow milk protein allergy. I had irritable bowel syndrom for a couple of years and this got better with a wheat, gluten and cow milk free diet (although western medicine doctors couldn't find any of these allergies!).

But now to the PN. I can imagine that the process you describe was en is happening in my body. But is there any way to stop this process? I've read about IVIG. Would that be a possibility? I don't want to get my hopes up to much, but just want to explore the possibilities.

I will take the methylcobalamin.
