I believe I have this, though with too much cortisol isntead of too little (is that the same thing?). I can't seem to get a concrete diagnosis of it, however. I did take a cortisol test a couple years ago, and it showed my cortisol levels were through the roof at the certain times of the day, especially late at night and early in the morning. I've tried to follow these tips and suggestions as much as possible, but my condition hasn't improved very much. Needless to say, the last few years have been a nightmare for me. It's interesting info, though. Thanks for posting.
