get plenty of sleep. your sleep is sacred and should be treated that way -- by you, by your manager, by your family. unfortunately, you're the one who is going to have to enforce that. don't take phone calls during your sleeping hours. unplug the phone, turn down the answering machine, whatever. if you must, have an emergency pager or cell phone that is to be used only if your child is hit by a truck, your parent has a heart attack or your hospital is demolished by a terrorist attack. use "black out" curtains, or a sleep mask, an industrial-strength fan or earplugs -- whatever you need to be able to sleep through the day. if your husband calls you at 1 pm to ask you how your day is going, return the favor at 1 am. he'll get it. eventually!
all the advice you have so far is good but this about your sleep is especially important.
it's been 10 years since i worked nights but i could go back to them tomorrow!!
i insisted on my sleep though. i used the earplugs, with a tape of ocean waves playing continuously, loudly enough i could just hear it through the plugs. no other outside noises got through. my phones were off, in case of dire emergency my husband could come home and wake me up (never happened). i also kept the room dark and cool.
a lot of people have no concept of what working nights means. you have to get your point across; if someone gets offended that's their
problem. (my sil seemed to think that doing her dishes after supper was "working at night." she got to bed before i ever left for work!!) i left a great big note on the door: night worker, do not disturb!
i'm still a night owl at heart!
good luck to you in your new position!
