Not diagnosed with adrenal fatigue, unless you count a self-diagnosis. I would like to get myself tested but I'm afraid that the results would turn up negative and I would be back at square one, again. Mine is mild, I guess. Not ready to fall down in a fetal position yet, and hopefully not anytime soon.
(I'm not much help though, I still do stuff that drains my adrenals, like drinking coffee/fasting/not getting enough sleep/ bodyweight exercises) I'm working more with diet and supplements to help heal them, though once my youngest is weaned I'll be able to start more aggressive treatments(adaptogens)
A good person to chat with on here is Zoebird, she's a yoga instructor. I think yoga can be great exercise, its a lot of flexibility, body weight, and to some extent cardio exercises. She might also be able to point out some yoga asanas(sp?) that can help the adrenals.
