I have the wired but tired symptom as well. Terms like alterness, vigil, red alert, electrically charged, etc are very meaningful to me. It's a really horrible feeling and outside the bounds of any nervous system state I have experienced in normal health. It was really bad during the early years of my illness. I would be awake for up to 50 hours. I would feel extremely motivated yet utterly incapacitated because of severe exhaustion, malaise and cognitive disablement.
