it really depends on the day, how tired i am, and annoyingly how much i need to fall asleep right then and there. a lot of the time if i know i'm getting up early the next day and i need to fall asleep *right now* to get a good amount of sleep, i'm wide awake. once i'm out i'm usually out for the count though, other than sometimes turning in my sleep. you can tell if i've been exhausted if i wake up and the duvet has hardly even moved because i've been stock still
