Has anyone hit a wall of insomnia AFTER adrenal improvement, like a cycling up of energy with nowhere to go? I have low average cortisol, with a less steep curve than ideal leaving excess cortisol in the late afternoon. I need to test evening levels of cortisol and adrenaline. Other hormones are low--epi, norepi,gaba,serotonin, dopamine. Four months into taking precursors my swings have levelled out and my energy was slowly increasing, but the last two months I have hit a wall--4 days of insomnia (avg 2-3 hours per night) followed by a week of good sleep, then repeat. I've read about phosphorylated serine as being needed to retrain elevated evening cortisol, but is that a common stage in the process of rebalancing as energy cycles up? I know insomnia can also be due to toxicity. I'm not hungry at night so I'm ruling out hypoglycemia as a big factor. What else can elevate cortisol four days on, seven days off? Is that a detox pattern? Does detox switch off when you reach a level of sleep deprivation? For the four days or so I can "feel" cortisol running in the background 24 hours, e.g. songs running through my head all day and night, alertness also, which I suppose could be adrenaline, too. CalMag, 5HTP, Tryptophan, Phosphatidyl Serine, GABA, Kavinace, Benadryl, adaptogens, Melatonin--not one of them or in combo does more than improve mood. The sleep "trigger" is missing when the insomnia cycle is "ON". If I do drop off I'm up again in a half hour like a stone skipping off water. Many thanks for your thoughts.
