I have a recurring problem where i sleep for 9.5 h+ most days, ever since july/august. in the past few weeks i have actually slept mostly 10h+, with the past few days being around 11h30m. the fact that i can't hear my alarms in the morning no matter what time i set them ties in to this problem. i usually sleep after 11pm or 12am; it is difficult for me to sleep before 11 due to my lack of willpower. but i have no clue why i keep sleeping so much and cannot wake up earlier w/o being woken up.
