The selling of quick solutions is of a piece with disbelief in the medical (and general) community. Indeed, the fact that we use language such as "believe," the language of faith, speaks to more than the invisibility of the disease on our bodies & on conventional empirical tests. There is a deeper aversion at work, which is facilitated by the word "fatigue," which people perceive as a transient state. "Fatigue" is something to be overcome, and our individualistic society cannot brook the idea that someone cannot master it w/o some flaw in our character.
