[Ixiaus]

I don't have any specific scientific papers to cite (although I have seen them), I do have personal anecdotal experience and this article that I read a while ago about it: http://www.integrativepsychiatry.net/adrenal_fatigue.html

My personal experience was this: extreme fatigue during the day (it was difficult for me to stay awake and not nap when doing anything sedentary), daily allergies that fired up (very badly) for no allergic reason, and a general sense of sluggishness.

Once I cut out stimulants (it isn't just caffeine, but the amphetamines in decongestants, ADHD medications, etc...) and started taking pills with desiccated adrenal gland tissue and thyroid boosters I could stay sharp all day long without ANY caffeine or naps. I slept really well every night, and a general sense of well being came back.

This coupled with my improved diet in general (paleo diet, no grains at all, high in animal protein and vegetables) made my life so much better. My body feels good, finally.
