Did you ever try phosphatydl serine? It was the main ingredient in an adrenal calming cream that I used to take and the only thing that calmed me down when I started going insane. Then I switched to the pills (seriphos formulation and brand apparently way cheaper and requiring way less digestion than others). It took me a while to realize that the dose in the pill was putting me into a sleep coma well into the next day, so I don't suggest trying it until you can sleep in. However, it turns out my adrenals are already totally shot and my total daily cortisol output is very very low and p.s. knocks down cortisol (OK, that's the best I understand it).
I couldn't understand why I could only take adrenal relaxants when I was so tired (exhaust rev). Any chinese adaptogen would have me climbing the walls after 3 days.
Am told that with way low cortisol, all one gets left is adrenaline - so I was always in fright or flight, starting to cry a lot and have anxiety I could not control. Then taking tons of natural relaxants all day until the next day I'd be konked out or in blessed sleep coma.
