If adenosine is highest (extracellular breakdown product of ATP) in the brain during sleep (The Role of ATP in Sleep Regulation) why would taking an ATP supplement disrupt, rather than enhance sleep?
I've experienced this with oral ATP (Swanson) as well. Should it be taken in the evening instead of the morning? Or twice a day in smaller dose? I am thinking that perhaps there could be a short term agonistic effect combined with a decline* in ATP levels that "starves" the brain of ATP, relatively speaking?
*Do you (@haidut ) know what the "half life" of ATP is?
EDIT: "Recently, it was observed in rats that ATP levels in several brain regions (frontal cortex, basal forebrain, cingulate cortex, and hippocampus) are stable during waking but exhibit a surge during the initial hours of sleep (Dworak et al., 2010). "
So taking ATP (Cardenosine) just before bedtime with a little food?
EDIT 2: "The hypnogenic properties of adenosine in specific brain areas have been demonstrated in many studies. Infusion of adenosine and adenosine transport inhibitors into the basal forebrain increases sleep in cats and rats (Portas et al., 1997; Methippara et al., 2005). Extracellular adenosine levels in the basal forebrain measured by microdialysis are lower during NREM and REM sleep in cats, while levels are increased during sleep deprivation and subsequently normalized during recovery sleep (Porkka-Heiskanen et al., 2000)."
"These findings suggest that adenosine is a sleep-promoting substance, decreasing the activity of cholinergic wake-promoting neurons in the basal forebrain that are presumably responsible for the accumulation of adenosine during prolonged waking (Porkka-Heiskanen and Kalinchuk, 2011)."
EDIT3: So the question seems to be, how rapidly is ATP broken down into adenosine (extracellular, in the brain)?
What I am finding is that I am sleeping very well for about 5 hours and then waking up.
However, I do NOT think it is cortisol. Fundamentally different. Waking up groggy (cortisol generates alertness) but unable to go back to deep sleep. Not anxious at all. Not hot (if anything, pulling the covers up because a bit cold. Not elevated pulse.
Could it be a (relatively) low extracellular adenosine causing? Would split doses (say, breakfast and dinner) eliminate? I am going to try this evening unless anybody has a clear reason not to.
