My SO works the late shift. I am blessed because I only work one 24 hour shift a week, so I'm able to keep to his hours and we have a "normal" family life because I can. Our bedroom is kept as dark as possible. I looked for lots of creative, NON TACKY ways to do this, but in the end wound up doing what he's always done; I put aluminum foil on the bedroom windows. The rest of the house has lined curtains, but they are quite expensive and available in very few styles anymore. The aluminum foil was cheaper and I can still have pretty curtains over it.
Change your whole life schedule to match your shift. Example: what we do is, when he gets home (around 1 - 2 a.m., sometimes later) we eat supper. Then we do our visiting with each other, maybe watch some TV, before going to bed around 3 a.m. and sleep till around 10 - 11 a.m. the next morning. We still have people that don't understand why we don't go to bed as soon as he gets home, but as he tells them, they don't go straight to bed when they get off @ 5 p.m., why should he? Most everyone knows not to call us before noon. To do so risks getting a very unhappy person on the phone. We don't do it now, but when he lived in town he had a sign on his door that said 'Day sleeper - do not knock'.
Expect to get a case of the blues after the first few weeks. Without alot of sunshine to boost your vitamin D levels, you may feel down. We open up all the curtains as soon as we get up to let the light in, but also take vitamin D3 supplements.
In short (although it's too late for that
) do everything you do now, only shift the hours you do it to match your work schedule. Oh, and beware that for the first few weeks your reaction time may be slower.
