 The statement added that the mean temperature of normal persons in the AM on waking is 97.5 °F, not 98.5 °F, and that many of the symptoms described by Wilson are nonspecific and typical of depression, anxiety, and psychological and social stress.It also notes that a similar set of symptoms occurs in the alternative diagnoses of neurasthenia, chronic fatigue syndrome, fibromyalgia, multiple chemical sensitivity, chronic Epstein-Barr virus syndrome, and chronic candidiasis.Finally, the Association notes that chronic supplementation with triiodothyronine (T3) is particularly difficult and problematic, since various tissues set their own cellular levels of this hormone by making it individually from thyroxine, and supplementation of T3 may overwhelm this normal regulatory mechanism in some of these tissues.
