Thank you for the reply. I heard that doses <20 do not shut down endogenous production of cortisol. I'm hoping that a low dose like 10-15 mg will support my adrenals to some extent and let them heal. Other supplements are not effective for me at this point. I tried about 5 mg of hydrocortisone today divided into 2 doses and felt a bit better. When I added a little bit of licorice root, the results were much better. I have not heard that licorice shuts down cortisol production like high doses of hydrocortisone can. I don't know at this point. Maybe I am deluding myself thinking I can reverse the damage I've done to my adrenals.
