On weekdays I sleep for 7 hours because of school.
On weekends I sleep for about 9 hours unless I'm like fucking tired and get a shit ton of sleep. Normally, I would pass out at around 2am and wake up at around 10am.
My sleeping pattern gets extremely fucked up during the summer. I sleep at like 5am and wake up at 4pm in the evening. However, it gets kind of easy to adjust to when school approaches since I just force myself to sleep.
