Man, I have done every single thing anybody here has listed so far, except for cold thermogenesis (I have Raynaud's and my hands/feet completely drain of blood if exposed to the cold - - highly unpleasant). Not one of them has done a damn thing. My bedtime rituals are ridiculously long and complicated at this point and I still don't get more than about 5 hours. It sucks, sucks, sucks. I am eating soooo clean right now, it is massively frustrating to feel like absolute crap all day, every day. Ugh. If anyone figures out how to get the body to stop pumping out cortisol in the middle of the night, PLEASE TELL ME.
