A medical reference book recommends for adrenal fatigue
Natural treatments for adrenal fatigue include vit C (3 gm/day),DHEA (50 gm/day)
L-theanine (100-400 mg/day, vit B5 (1500 mg/day), Phosphatidylserine (300 mg/day), Licorice (no more than 1000 mg), Melatonin (300 mcg to 6 mg at bedtime). Limit processed foods, alcohol, smoking.
Have you had your DHEA levels checked? Most with adrenal fatigue are deficient.
Note also that mercury from dental Amalgam fillings and toxics are common causes of adrenal fatigue and chronic fatigue http://www.flcv.com/endohg.html
Do you have several dental Amalgam fillings? Those that do get 10 times as much mercury exposure on average as those without, and over time commonly develop chronic health problems http://www.flcv.com/damspr1.html
