Addison's disease can not be cured with rest. Alot of folks have naturally low cortisol levels, and because of that resort to abusing stims, which only worsens the problem.
indeed. but MOST of the time, subjective burnout feelings occur while free cortisol and and DST tests come out normal. (some users have posted this, including me and RAS).
what really happens is a shift in the hypothalamic HPA setpoint. this, as I alluded to, is what is subjectively referred to "Adrenal burnout" more often than not.
Here's what I think happens(how we got there is a diferrent issue)
fucked up GR/MR ratio coupled with changes in CRH pulsatile secretions and inflammtory circadian rythm.
Normally, inflammation peaks at about 1 AM(tnf-a levels) (or earlier) and Cortisol peaks at 9 AM or earlier. OTOH, CRH is essentially inversed. that is the normal state of things.
since both are dependent to some degree (with latency)on blood sugar levels, arousal, activity and other factors and on each other, when they are perturbed as I purpose, they are not inversley correlated anymore.
CRH still has a peak in the morning although blunted because the delay in inflammation peak, but you still have hypo and arousal, so its still up. fucked GR/MR ratio means that resulting released morning cortisol will blunt cortisol release too much. so you will still be foggy, even tough some inflammation will subside. come late evening, arousal, feeding patterns, coupled with lack of daily CRH negative feedback will spike CRh, preventing inflammation to ramp back up to its nightly peak and delaying this peak.
So you have:
morning:normal cortiosl but high inflammation, resulting in drowsiness
during the day:low cortisol, normal inflammation, resulting in drowsiness
evening: CRH starts to rise but still no cortisol response.
night: relatively high cortisol, low inflammation, resulting in poor sleep
as you can see, CFS sufferers have normal DST resuts if you look only at morning, but the effects last way too long. this is because of the GR/MR ratio.

OBJECTIVE: Subtle dysregulations of the hypothalamus-pituitary-adrenal axis in chronic fatigue syndrome have been described. The aim of this study was to examine the negative feedback regulations of the hypothalamus-pituitary-adrenal axis in chronic fatigue syndrome. METHODS: In 21 patients with chronic fatigue syndrome and 21 healthy control subjects, awakening and circadian salivary free cortisol profiles were assessed over 2 consecutive days and compared with awakening and circadian salivary free cortisol profiles after administration of 0.5 mg of dexamethasone at 11:00 PM the previous day. RESULTS: Patients with chronic fatigue syndrome had normal salivary free cortisol profiles but showed enhanced and prolonged suppression of salivary free cortisol after the administration of 0.5 mg of dexamethasone in comparison to the control subjects. CONCLUSIONS: Enhanced negative feedback of the hypothalamus-pituitary-adrenal axis could be a plausible explanation for the previously described alterations in hypothalamus-pituitary-adrenal axis functioning in chronic fatigue syndrome. Because similar changes have been described in stress-related disorders, a putative role of stress in the pathogenesis of the enhanced feedback is possible.

Objective: Chronic pelvic pain (CPP) and fibromyalgia syndrome (FMS) have been associated with hypothalamic-pituitary-adrenal (HPA) axis alterations, i.e., mild hypocortisolism and enhanced feedback sensitivity. We tested the hypothesis of reduced cortisol release in response to a psychosocial stressor and pharmacological stimulation. Furthermore, glucocorticoid (GC) sensitivity was evaluated.
Methods: Plasma total and salivary-free cortisol concentrations were measured in response to a standardized social laboratory stressor, the Trier Social Stress Test, and to adrenocorticotropin (ACTH)1–24 stimulation. In the Trier Social Stress Test, we additionally measured ACTH. GC sensitivity was measured by dexamethasone inhibition of lipopolysaccharide-induced interleukin-6 and tumor necrosis factor-alpha production in whole blood.
Results: There were no HPA axis alterations in women with CPP (N = 18) in these tests. Patients with FMS (N = 17) showed lower total cortisol release in response to the social stressor and exogenous ACTH, but normal free cortisol and ACTH levels compared with controls (N = 24). GC sensitivity was similar in all groups.
Conclusions: Our results suggest normal HPA responses to stress and ACTH stimulation in patients with CPP but reduced adrenal reactivity in patients with FMS, namely in total cortisol release. Free cortisol on the other hand was unaltered, possibly reflecting an adaptation to reduced circulating total cortisol.

... is that I tend to display a "fear" response (unintentionally) socially at times. I do try to smile, but I think it's that my brow muscle tends to pull the top of my eyes up, judging from the singular skin crease on my forehead, which is part of the pattern of muscle activation of the "fear" response. I don't actually feel fear...
I've been told that people that don't know me find me a little intimidating because of my body language, for instance when I go "WHAT WAS THAT?" if I didn't hear what someone said. they skulk and say something and I just don't get why they are frightened. that's funny as hell to me because I wouldn't harm most creatures (I would harm a fly though. on occasion). I was not sure where I got that body language.
Ofcourse, in the context of hyper CRH/low cortisol, it all makes sense.
this is why regular morning DST sucks balls. if you have DSPS
