Re: how does cortisol work??

The symptoms are the same for too much or too little cortisol.  You would need to do the saliva Adrenal Stress Index test to find out.  Compounding pharmacies carry the saliva kits, then you send to a lab.  There are many stages to adrenal fatigue, 7 altogether.

This site gives a good rundown on how adrenal fatigue progresses and what the hormones do, including cortisol.
