My guess is that your adrenals are all whacked out from lack of sleep, caffiene intake, poor nutrition etc. They will regenerate as you keep up your healthy habits (good job, by the way) but you may even consider something like an herbal supplement to help them adjust. Something like Siberian Ginseng is good and not too stimulating (panax or korean ginseng is more stimulating), licorice root (not long term), ashwaghanda, etc are all good. Milk Thistle would be great for your liver which has probably taken a beating too.

Lots of B vitamins and vitamin C will also help the adrenals. DHEA and pregnenolone are hormone precursors that the adrenals can use to make cortisol and its other hormones, but although you can buy them OTC it pays to be more prudent with taking them. Many people find they really help with energy and emotional stability.

I hope this helps. If you have any Q's feel free to email me. I'm a naturopathic doctor so I'm really into this stuff!!!
