multiple sclerosis
"Started taking 3-4 yrs ago in early 50's while transitioning from RR into SP. Early on saw subtle improvement with only mild constipation, but was unable to go without AFO.  Past year in SP, balance and gait worsened where use AFO & cane fulltime.  Decided a month ago to stop taking.  Balance much better.  Gait seems unaffected.  Living  with SP is definitely different from RR."
