This is another word for the state of being tired.
Lack of energy seems to be very common among those with Ataxia. For me anyways, the supplement CoQ10 is vital. I take 1200 mg per day. Unfortunately, this over-the-counter supplement, recommended by most neurologists, is very expensive. I have found this site to be my best option: http://m.puritan.com/co-q-10-055/q-sorb-coq-10-600-mg-030454 ; through them I will buy 5 bottles of 600 mg for $79.98 (Buy 2 Get 3 Free). This will last me just over 2 months.
