I had b12 deficiencies, and had horrible brain fog for a few months. I didn't have any severe nerve issues like burning or numbness, but I think my myelin sheath was significantly damaged.
1) Is it possible to make a full recovery?
2) How can I assess damage ?
3) How long does it take to regenerate myelin sheath fully?
I am in a b12 treatment that is going well according to the significantly reduced brain fog and fatigue symptoms.
