First of all, congrats on your dream job!
I have worked all shifts, but for the past few years I've been working nights. It works out best for my family and for my school.
If my husband can get the kids ready for school, a lot of times I will stay up very late the night before I start working. I use this time for household management, cleaning (if it won't wake others), watching a movie, reading a book, etc. I consider it a bit of "me" time. Then I sleep as long as I can the day that I have to go in to work.
If I have to be up in the morning, or can't sleep in, I try to get a nap or just lay down with a book or a crossword book. I get as much rest as possible, and just a couple hours' nap can usually sustain me quite well. These methods work well enough that I am usually able to forgo caffeine as I dislike coffee and I'm trying to get away from sodas.
Sometimes I take a benadryl *very* early if I think I won't get sleep. I try not to do that either.
For weekends, I have a set of earplugs that work great. I usually don't hear anything until the alarm, and sometimes even then my husband has to wake me up.
Overall I really enjoy nights and doubt I'd go back to days in a clinical capacity. The work is a little slower paced (maybe not as much in L&D LOL), there are fewer people wandering around, and I have a great group of coworkers. Good luck
