I'm surprised there's no way to medically "force down" one's cortisol or epinephrine just for a few days. I understand why drugs that do this permanently, like for Cushing's Disease, are dangerous if you don't have Cushing's, but why can't there be treatments just to lower these chemicals down temporarily? I feel like it would at least give the patient information about whether or not high cortisol, or cortisone, or epinephrine, is causing their CFS symptoms.
