Starting Nightshift Tonight

I'm starting my last brief (2 day) orientation on nightshift tonight at the LTC. I had 4 days of dayshift orientation and 4 evenings of orientation, the last two weeks. Now tonight I start nightshift. I haven't done this shift since I was a young thing. I am concerned how well my 51 year old body will take it. It should be an easier shift than day and evening. I already have a schedule of duties, which of course will be flexible according to the type of night we have there. I was tired last night from all the moving the last 4 weeks and orientating to my new job and tearing up the floors in our new home, plus painting. I slept 12 hours!

I planned to take a short nap this evening, yet my 17 year old kept knocking on the door, to ask silly questions. I have to talk to him about not knocking on the door, unless it is an emergency, he has his big brother and step-dad to talk to in the evening.

I really want to give this a try, if it doesn't work I'll look elsewhere, but at least I want to give it a good try, I like this LTC. Any advice and tips how to survive the nightshift?
