On holiday, anywhere from 1-2am to 10-11am.
I would sleep in, but I'd gradually mess up my sleep schedule because I'd keep going to bed later and later.
During school days, I'd sleep from 9-10 to 5-6.
I'd like to get more sleep but according to my classmates who fall asleep at midnight or later and wake up at like 7 they would dream of being able to sleep as much as I do.
