Please have a look at the article on the link below. Even the diagrams are useful. I have always felt the EBV link would eventually be established and have taken Avonex and Valtrex for over a decade which now looks like a reasonable practice to have pursued. (despite hating Avonex for its side effects). I have a potted history of what I have been doing under the Regimes section of the forum under the heading of Avonex and Valtrex. I will now seek some medical advice about the right sort of Vitamin D and add that to the process.
Please read the attached. It's the best thing I've seen on MS ever.
