In my own life this hasn't been much of an issue. I wake around 5pm, so if there are evening plans, that tends to be my morning plans. Of course, this means I end up having a fancy dinner with friends for breakfast at times, but that's not all that big of a deal. And if I plan to work that day, I won't drink at "dinner". All in all, my social life is pretty normal with my night schedule. I wake up around the time my wife gets home from work. We eat together and talk and hang out. When she goes to bed, I go to work. By morning, as the rest of the world around me is waking up, I handle any errands or chores and I'm back to sleep by somewhere between 9 and 11am. The only time my schedule ends up being an issue is when we travel. But then since I'm not working, I actually really enjoy being up during the day. It's just difficult to switch schedules from "night mode" to "day mode" and back after our travels are over. It's pretty much the same thing as jet lag when flying half way around the world. It's a pain in the ass for a couple days, but not particularly detrimental.
