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.

anecdotally i feel pretty good when im buzzed but reality is my performance is impaired. there is a teeter-totter of overconfidence and impairment where the liquid confidence actually helps more than the impairment impairs but its a sweet spot

sleep deprivation definitely reduces raw reasoning ability. in some cases, though (and this is true for getting buzzed as well) the trade-off is absolutely productive.
