Dawn. very interested in this worm therapy you mentioned. I have looked it up and it sounds interesting. You also mentioned that it was available in canada but can not seem to find anything about that. Do you have any info in regards to that?? I am no longer able to tolerate ivig. I am going down hill fast. i have an apt. with specialist may12th in Vancouver. i want to ask him about sub Q ig and other options so any info would be great so I can take it with me.
