I'm interested in the topic of remyelination as well. In doing some research, I came across this organization: http://www.myelinrepair.org/
This group of researchers is about an hour away from where I live. Their collaborative team approach gives me great hope. And of course, they're not the only ones doing research.
Assuming they cured MS tomorrow, they will still be pushing to find a way to repair myelin, and not just for MS but for other diseases and injuries that damage the nerves.
My intuition is that the body wants to heal itself whenever possible, and certainly you can help it with the right additions/subtractions/substitutions of foods (the fuel your body needs to live) and supplements (also fuel). So go ahead and take credit for the positive changes you've made. You deserve it.
