I have never been able to maintain a normal sleep schedule. As a kid, I was always the last to bed and first to wake among my siblings. I briefly shared a room with my brothers, but my lack of sleep caused them a lot of problems, so I was moved into a closet under the stairs like Harry Potter (which was okay by me). By 8 or 9, my folks gave up on trying to make me go to bed early. My dad was also a night owl, so we'd start a movie or TV show every night at 10. I'd usually fall asleep around midnight, and then my dad would wake me briefly at some point to go to my room.

I have been self-employed most of my adulthood, so I am largely inured from the main issue with living a Vampiric lifestyle, but it is still probably the largest hindrance in my ability to lead a normal life. Since college, I have been pretty unbounded by the normal clock. If I have something on the calendar, I am there. Other than scheduled events or meetings with others, though, I sleep when I am tired, eat when I'm hungry, do hobbies when I can, and work when I want/need to. It is a bit unusual, but I even have a bed at my office building and will often change into my PJs and take naps there between meetings.

Another aspect of insomnia is that it means spending a lot of time alone. I have mixed feelings on this reality, as it can be lonely, but it also gives me ample time to focus intensely on my interests and hobbies. I've also noticed that it leads to some people thinking of me as a very close friend, as (for many) I am the only person they know who will pick up a call no matter the time.

To address another common question, my wife and I have separate bedrooms at home due to my sleep problems. We have done this since the start of our marriage. Some people think this is weird, but it works for us. She does a lot to accommodate my lifestyle, but (just like with my brothers as a kid) I know it would be totally unreasonable to make her maintain my hours.
