Similarly, apnea also leads to elevated cortisol levels. One study found that subjects had 50% percent higher cortisol before CPAP when compared to after.  This is truly nasty: cortisol is not something you want elevated by even the smallest amount. Higher elevations, especially in the middle age and beyond years, can lead to memory damage, lowered testosterone and a host of other ills. I also recommend that you read my link on Natural Apnea Solutions . In the last ten years researchers have uncovered the fact that most apnea is actually lifestyle-related and not simple genetics or aging.
Hmmmm interesting. Funny you mention it because I was taking gaba not too long ago and it was in a mixture with some other stuff. Anyways, I think it was causing me to wake up kind of uncoordinated and feeling just kind of weird. Dissociative I guess you could say, which makes sense because it’s related to the NMDA receptors somehow I think. It supposedly “can’t” cross the blood brain barrier, at least this is repeated despite the fact that it can and does, it’s just an unreliable mechanism in which it does. Low levels of gaba were insinuated to absorb more in the brain also. I didn’t have this issue as if I took the full 750 mg I felt very strange consistently and none of the other supplements in the mixture would seem to do this.
