anyone notice poker players completely forget strategy when tired

I keep seeing this at the low stakes tables, especially after midnight - guys who were playing sharp suddenly start limping into garbage and bluffing spots where nobody's folding. It’s wild how just a couple hours longer and the logic is gone. Blackjack and roulette folks seem to stick to their routines way better, even when they're dead on their feet. I wonder if it’s because poker forces you to make more constant judgment calls, so fatigue just wrecks you quicker.

Anyone actually work on a plan for this or have ideas for keeping your head clear late at night? Or is it just inevitable everyone slips when tired enough?
