My best friend did it for a while in college on top of his other job at a video store. He worked the shit shift (11pm-3am), and he was miserable. The pay was good, but you don't get any benefits until you've been there for 30 days, and you're pretty much never allowed to take time off. He couldn't even go home for Christmas because he had to work.
If he hadn't been going to school and working another job at the same time, it probably would have been a lot better for him, but at the time it was terrible. He even failed a couple classes because he never had time to sleep.
