I was diagnosed with adrenal fatigue, but it was not episodic. I had been tapering off of Prednisone after a course of several months of steroid treatment. The conclusions that I remember from the situation were thus: I had been on steroids too long, my body had forgotten how to function without them, and tapering off by 5mg a week was too quick. We switched my taper to 2.5mg decreases and the symptoms went away. I don't know a lot about adrenal fatigue, just that when it was at its worst I could barely CRAWL from the bed to the bathroom. But again, it was only bad until I slowed down the taper... and after that I had no reoccurring issues. I would definitely get some blood tests before you go spend a bunch of money on supplements... make sure you're on the right track.
~Best of luck.
