I fall asleep easily, but frequently wake up at 2:30AM and have trouble getting back to sleep until 4:00AM, which is just an hour before I would normally get up. It does kinda suck, but I'm sure it could be a lot worse.
I used to keep my old physics textbook next to my bed. Interesting enough to find something to read, dry enough to put me to sleep in a couple paragraphs. Ha!
