I think it takes a lot of time and tweaking your schedule to feel ok when working nights. I usually have trouble wanting to go to sleep when I get home in the morning. If I force myself to go to sleep, I usually feel pretty good when I wake. I work 5 nights on and two off. I sleep at nights on my days off, and days on my nights on. I take a nap before the first night back.
The hardest thing for me is to wake up, and everyone is waiting for dinner, and I can't even think yet. I want my coffee and donut, and leave me alone for a little while. But, if you eat (breakfast) you won't be hungry for dinner.
But, I have worked nights for 15 years, and it has worked well for me. I have found activities that meet on my days off. This way, I don't have to leave a function early because of work. It takes some creative planning. I do miss somethings, but I have missed things when I worked days too. I really think the bummer of a shift to work would be the evening shift.
I am free to go to school meetings, and shop during the day. However, I need to plan my sleep around that as well. People know I usually sleep during the day, and leave me alone. However, I don't mind a quick phone call once in a while. Another good thing, I am always available if my kids get sick at school, or miss their bus.
On nighs that I am tired, and maybe a little ticked off that I am carrying a larger load than my fellow day/pm shift nurses, I use that [angry] energy to push me through my rounds. It really spurs me on, and work then gets done even faster, and then I feel better.
