If I'm actually being productive at bed time, fsck it. I'll get back in sync later.

But, I think most of the time I stay up too late, I'm not actually accomplishing anything. I'm either playing games that I will enjoy just as much, maybe even more, if I practice good sleep hygiene. Or, I'm letting some recommendation algorithm drip-free me neurotransmitters, and that's not worth disrupting your sleep routine.
