does anyone else study better when theyre slightly sleep deprived

weird one but bear with me. whenever i try to study fully rested and caffeinated and ready to go i end up overthinking everything and getting nowhere. but when im kinda tired and its late and i just want to get it done i somehow focus way better.

its like my brain stops second guessing every sentence. happened again last night, crammed like 3 chapters of econ in 2 hours at 1am which would normally take me double that.

idk if its the sleep deprivation or just the deadline pressure kicking in. anyone else notice this or is my brain just broken lol
