Hi Lyn, your experience with ON, sounds exactly like mine, right down to the fog.
My first big exacerbation was way back in 1974. I didn't have ON then, but my 2nd big attack, after a glorious 18 yr remission, was in 1992, and that one started with ON.
My Mother was also dying, she died in 1993. Maybe there is something scientific to this phenominum, about Mothers and MS. My Mom didn't have MS, but my Daughter does.
I didn't have any lasting effects from the ON, but did have to get new glasses. They are on my face, in my Avatar..LOL. that Pic was taken in 2000, I was 60 and 35lbs lighter.
Hugs,
