I share your view that insulin is involved.
In fact, it was through your thinking and interaction with yourself that I started the topic on A new concept for MS in Jan 2011.
But besides the insulin factor, I think MS is a broader issue of endocrine dysregulation.
Where at some point in the disease process, the HPA axis gets affected establishing a vicious circle.http://syontix.com/the-gut-brain-axis-h ... enal-axis/
I also believe that stimulating insulin may help to feed the crying cells, a bit contrary to your believe.
I still take some metformin and glimperide, for what it is worth...
