I got my first experience as an LPN almost 16 years ago in LTC working nights. I thought it was a fine place to start. I wish you good luck.

There are lots of threads on allnurses about sleep on the noc shift. Really, really try to get at least 6-7 hours of uninterrupted sleep. Use a fan or something for white noise so the sounds of the day don't keep you awake.
The night shift can work very, very well for some people. Most of folks I used to work with continue to work nights. It allows people to spend evenings with their families and not miss activities like those working 3-11.
