What is your advice on what to do for adrenal fatigue?

See endocrinologist: "adrenal fatigue" is often a fake diagnosis. The adrenal makes cortisol and adrenaline, which are stress hormones. People who are stressed are sometimes persuaded that it’s the adrenal’s fault. This is usually not true. Poor adrenal function is determined by an acth (cotrosyn) stim test, and not by symptoms alone or measuring just one blood or saliva level. See an endocrinologist.
