It's strange that you'd have insomnia while having high dopamine and low norepinephrine. That combination of markers could cause drowsiness in some cases, but obviously not in yours. My guess is that's a symptom rather than a cause of what you're dealing with.. I hope you're still with us; you haven't posted in over 3 weeks. Hopefully that means you've been too busy sleeping and enjoying your waking hours.
I experienced a 2-week period of sleep deprivation a year ago, while I was travelling. I was using 4-FA and 5-APB every day, and they were still active at night to the point where I'd spend the entire night in the back of my car blissfully resting, but never falling asleep. I thoroughly enjoyed it, as I spent every night parked on remote dirt roads in the vast open spaces of the western US, but after 2 weeks I suddenly went completely incoherent and my brain simply shut down. I was at my sister's house, washing dishes, and I'd been in a great mood that day, but in about 2 seconds I experienced the absolute dissolution of reality. My brain couldn't organize sensory information, and I had to lie down on the kitchen floor, much to the distress of my hosts. When my sister was able to get me to respond, I just burst into tears because I was so confused that I couldn't communicate with her.
For the next 3 days, I went through a bizarre Alice In Wonderland journey of psychosis and sleep that was saturated with extreme dreams. I had never gotten out of bed in my sleep in 58 years of living until one of those nights, when I got up in the dark and started piling every physical object I could find into a corner of the room in a chaotic jumble, and my sister woke me up asking "What are you doing?" I thought I had just flown a UPS plane from San Francisco to a town in Pennsylvania, and I was moving everything out of the way so that there'd be room for the plane to take off again. I was straight-up nuts. Of course the drugs I had been consuming during the preceding weeks surely contributed to the bizarreness of my experience, and I hope you haven't gone bat-shit crazy yourself after what you've been through.
I honestly have no helpful suggestions, other than to do everything in your power to get medical attention. If you have to lie about symptoms then do it. I'm shocked that you'd be dismissed so readily by your emergency rooms. Supposedly you have a good health care system, but that's insane that they'd fail to treat you. If you're still needing medical attention, then look up the symptoms of extreme sleep deprivation and say that you have the worst of whatever you find. There's no way you can have anything like a normal, enjoyable life in your situation. Ultimately it will kill you, and that's what ERs are supposed to prevent. See if you can fake psychosis. That could even be fun, although they might strap you to a gurney and inject you with something worse than hell, so maybe don't do that. Good luck, please post again to let us know how you're doing.
