I have never taken any MS disease modifying drugs. I do periodically think about trying LDN and I may still do that. I hang my hat on the benefits of high dose vitamin D and a low saturated fat, high veggies diet. So far its working pretty well. Its been a few years since I had an MRI but the last one I had showed no disease progression.
I don't think you're being foolish to stop the DMD's. What I always say is that I've got enough problems just having MS. Why would I want to add the dangerous side affects of the MS drugs to my list of problems! ...I guess implicit in that is that I don't have confidence that the DMD's work, or at least that they improve more problems than they cause.
However, having said that, I totally respect that its an individual choice, and since ultimately there's no way to predict the future, we all (including me) are taking chances when we make these decisions about what meds to take or not take for our MS.
My own philosophy is that I try to give my body the nutrients it needs to heal itself, while at the same time reducing my exposure to toxins.
P.S. If you haven't read up about high dose Vitamin D, there's some pretty interesting science that suggests it modulates the immune system in a helpful way and reduces MS relapse rates.
