anecdotally, i never feel better than when i haven't slept. spent 8pm tuesday -- 8pm thursday this week awake nursing cheap energy drinks, and not only could i manage a higher-than-usual level of focus, i was genuinely content.

bombed a midterm halfway though, but at least i felt good about it.

Age sounds like a factor here. I know zero long-term healthy ppl in 30s and beyond who act/think this way.

Indeed, as a 20 year old I would stay up all night pretty regularly for work and occasionally fun. At 40 I'm not sure I would live through it, at least not in a cognitive state where I could converse.

I've done a few all-nighters in my 30s and 40s, and they generally feel the same as my 20s. Still get that clear headed, high focus second wind around 4am that carries through until noon or so.

But, I definitely crash harder than I did in my 20s and need longer to recover after. In my 20s, would be fine if the next night was a normal one, now it takes multiple days.

It's definitely something I try to avoid at this age, as opposed to just being standard procedure back in college.
