FWIW, Mrs. LS diagnosed around 1995 with MS, took an interferon for about 7-8 years. It made her horribly sick every weekend when she had to inject. Finally, she just quit cold turkey.
No progression of the disease since then. Every once in a while, especially with very high humidity, she has an “episode,” but these so far haven’t been permanent. Given the loss of living time she had while sick from the interferon, she hasn’t regretted giving up the med.
She’s had no progression? That’s a wonderful thing to hear, but it’s very rare.
That is a true blessing!
