chronic fatigue syndrome
"I had CFS for 7 years and when I had an episode of the illness I would be bed ridden for six  to nine months. Doctor gave me Amantadine in hospital and I instantly fell much better. Now I take it when the disease starts, I take from one to 3 daily for about a week. It helps me function normally and it always gets me out of the bed. When I way taking it for a longer period it would start to cause symptoms similiar to the dissase so the best way for me is to take is from time to time when I feel I have a relapse."
