@Drentel - I too once worked the graveyard shift. I liked the quiet of working third in the hotel where I worked. Well, it was quiet during the week, not so much on some weekends.
Anyway, like most third shift workers, sleep was my biggest issue, too. Some days i went to bed immediately after work, Some days I stayed up until the afternoon. Either way, I found that I could sleep much better when I had some type of white noise to fall asleep to. I mostly used a portable fan, which made just enough noise to drown out all the other noises in my apartment and the surrounding apartments in the building.
Sometimes I would fall asleep to the radio, but at some point I would wake and the music sounded like it was blasting much louder than when I fell asleep, or the DJ talking would be screaming at me.
