Some “official” info on sleep deprivation (thanks, Jade), quoted in pertinent part only:

With enough sleep deprivation, it has been found that some begin to
hallucinate and develop mood swings. Higher-ordered cognitive tasks become
more difficult to do where it has been shown that tests that require speed
and accuracy have lower results compared to those that are not sleep
deprived. Judgment is also impaired; it has been tested that riskier
behavior is more likely to occur when sleep deprived.

Had I known yesterday that I’d have a medical, scientific, biochemical excuse for my behavior, I would’ve done more stuff.

(Of course I’m kidding. I think. Don’t think less of me; my judgment’s impaired.)
