I did 4 years of nights. The real trick is being able to sleep during the day. So whatever ear plugs, face mask, blackout curtains you need, make sure they work for you. I generally would work up to it staying up until 2 AM, then 5 AM, then going to work. I believe that most people found that they had more time with their family because instead of being at work 8-12 hours during the day, they were only sleeping 6-7, and were home when their kids were getting up, going to school, coming home, etc.
Therapy is the best hobby.
