I worked 10pm - 6:30 AM a while back, I did it for about 5 months. It really kicked my ass, couldn't sleep cause of the noise of the city, couldn't stay awake at work. Driving home towards the sunrise is usually bad policy. For me it's not worth it, you get to work with some freaks (which makes things interesting) and usually graveyard shifts are more lax with better pay.

Bottom line, if you are young you might as well try it for a bit, worst case you make a few bucks and then quit it's a perfectly good reason to say you quit when you are looking for your next job.
