i go to bed between 2 and 4 30 am pretty much every night. it's just always really hard for me to get to sleep. however much sleep i get depends on if i have class the next day, and what time class is. otherwise, i sleep until i feel like waking up. sometimes i'll get 3 or 4 hours, sometimes i get 9 or 10 hours. it just depends on what time of the week it is, whether or not it's summer, and whether or not i have anything to do the next day.
