Have you ever heard of Chronic fatigue syndrome?
1_Wizard
I have! My aunt suffered with it for many years. She was diagnosed based on her symptoms, I don't think a clear diagnostic test exists. Have you known anyone who's had it?

I have not, it sounds like something that would be awful, what are some of the characteristics of it?
1_Wizard
It's fatigue that is not due to strenuous exertion and rest doesn't really provide much relief. It's not due to a previous medical condition, so its cause remains somewhat of a mystery.

Oh no, that is awful, so I assume they have no cure for it then
1_Wizard
No, unfortunately not. There is no cure and no medications or procedures to treat CFS have been approved in the US.

Darn, is it pretty common in the United States
