This might sound weird, but sleep deprivation. I know it’s unhealthy, I only did it when young, but it was a rush to not sleep reading or gaming all night, then go to work/school. My record was 72 hours awake (Friday to Sunday) and while my head was wonky, and sometimes I would get very mild shakes, it was a high feeling still in control.
I’ve only felt a similar rush while fasting for several days, but for me it was much harder not eating compared to not sleeping.
