I have been plagued with bad sleep for years. I have no problem falling asleep, but several days a week I will wake up in the early morning hours and feel like my nervous system is on overdrive. It's like I have the uncontrollable urge to flex my arms and legs and I have to get up and walk around for a few. Eventually I'll lay back down and fall asleep again. I've always suspected that I have some kind of adrenal fatigue from partying so much in my 20's and burning the candle at both ends. Everything that I read says that cortisol should be low at night, and that high cortisol levels are stimulating and could affect sleep. However when I take supplements at night that reduce cortisol (such as Cissus or Phosphatydlserine), it seems to make it worse. Are my cortisol levels getting too low at night, to the point that I am having low blood sugar fits? I've done a sleep study before and they said I have very mild sleep apnea, and that I could benefit from a CPAP but it's not life-threatening or anything. I just feel like it is hormone related and that is what is messing with my nervous system. Anybody else ever have anything like that occur to them as well?
