Yeah I had adrenal fatigue and still have it in many ways. I would say probably stage 3 adrenal fatigue, because of the sympathetic nervous system dominance. My fatigue wasn't "can't get out of bed" bad, but it was still pretty bad. I couldn't drive more than 15 minutes without getting really sleepy. Going through school was really shitty too because I was always falling asleep.
It seems the adrenals are much slower to heal the some other things. But it's coming along.
