Night owl married to an early bird. Oldest is an early bird, younger was a night owl.
Night Owl - my natural sleep cycle is to sleep from 2am til 10am. This doesn’t generally work out well in civilized society, so right now I’m shoot for 12:30 to 8. BTW, the name for this particular sleep disorder is Delayed Sleep Phase Syndrome
Another night owl here.
Interesting board demographic. So far, the night owls waaaayyyy outnumber the early birds.
I have a job where I can set my own schedule. I will stay up until usually between 1 and 2 am and get up around 9.
I really think I would prefer being a morning person but it may be just that grass-is-always-greener thing.
Night owl. Or, more accurately, “guy who doesn’t sleep much”. Depending on my situation, I can take my choice of:
- Three to four hours nightly
- Eight hours every two days, staying awake for 36+ hours in the meantime
- Ten hours every three days, staying awake for 60+ hours in the meantime
and I’ll be just fine. Generally, I go with the second option (such as tonight, when, having gotten eight hours last night, I’ll be staying awake all night and going on a trip with some friends at 8:00 a.m.). A two-day cycle seems to work out best for me; I’m awake at night for some “me time”, and I’m also awake to get stuff done in the morning (I work during the afternoon). I use the first option when I have a lot to do over a period of a few days that requires me to get up early in the morning. It came in very handy in high school. I use the third option when I have a lot to do over a two or three-day period. We’re talking crisis zone here, where I’m too busy putting out fires or planning what to do next to sleep for even a few hours. You’d think that wouldn’t happen very much, but then, you don’t know me. I tend to get screwed over quite a bit.
As I said, though, given the choice, I operate on a two-day plan. Being awake in the middle of the night kicks ass. To all the other night owls out there in SDMB-land (and it looks like there’s a bunch o’ ya): good choice! 
Early bird. I like being up and about when nobody else is - I find it calming.
Plus, I hate running around in the morning, I like to be able to relax with a couple cups of coffee before getting ready for work or whatever.
Lifelong night owl, posting at 1:15am my time 
Used to be a night owl, but now am more of an Early Bird.
I almost never stay up past 10 or 10:30 and am almost always awak by 5 (if not earlier). I can stay up late if the need arises (usually movie-related) but it’s pretty rare–I enjoy going to bed with Mrs. AG and don’t feel liking I’m missing much (typically on TV) by not staying up. If I were to begin staying up later on a regular basis, it would be to do more recreational reading (though I still wouldn’t want it to interfere with me getting to work early).
Night Owl…no doubt about it. If I am writing I am most creative in the wee hours. I have been known to just stay up all night if I am really in writing mode.
I’m married to an Early Bird so sometimes I am up early also. I see the beauty of that, the day is fresh and new and crisp…but I am sure I will always be just an appreciative visitor in earlybirdland. 
Night Owl reluctantly turned Early Bird. Every other week, I have to be in the office at 6:30 a.m., so I get up at 5:30 a.m., which is something I *never * expected to be doing regularly.
Early Bird, most definately. Always have been and probably will be until I die. “Sleep in late” for me is 7 am. I usually wake up in the mornings by 6:10 (without an alarm clock) and I’m ready for bed by 10:30 or 11 pm. On the weekends, I get to take a nap (which usually lasts an hour on the dot), but during the week, my job interfers with napping, so I don’t do it (drat).
TMI…Oddly enough, I’ve charted my sleeping habits with my menstral cycle. On the few days (usually about three) right before my period starts, I want sleep, sleep, sleep, and will usually go to bed around 9:30 at the earliest and sleep like the dead all night through and wake later than usual. This is especially true during the winter. In the summer, it’s less time, but still more than usual.
Early bird, checking in.
I’m up at 6:00 a.m. every day of the week. I can’t really recall the last time I was up at midnight - I’m guessing it was New Year’s Eve, but I may not have made it that night either.
Night owl. I’m lucky if I’m in bed by 11:30 on a work night.
No matter when I roll out of bed, it takes me at least an hour to fully wake up.
Night owl, definitely. I have been since I was a kid. I’ve tried several times in my life to adapt to morning hours and it just doesn’t happen for me. If I get up before noon I’ll feel sluggish for at least 1-2 hours no matter how much sleep I get the night before. If I go to bed at 4:00am and get up at 1:00pm I feel great all day. I work from 11:00am to 7:00pm and even that requires me to get up at 9:30 in order to have enough time to wake up and be functional before I get to work. On weekends and holidays I immediately revert back to staying up all night and sleeping through the morning. I suspect there is a genetic connection as I’ve always had trouble dealing with mornings since I was a young child (going to school was hell), and my father and sister are the exact same way. My mother’s the only morning person in our family.
I used to be a night owl when I was a full-time musician. We’d be playing in clubs and tearing down until after 2 AM, then go home or to somebody else’s house and play some more (or whatever musicians do) until 5 or 6, go home to bed about 7 and sleep until 3 or 4.
Now, much to my dismay, I’ve become an early bird. I work a day job, and I could sleep until 8:30. However, something seems to be wrong with my internal clock, because now I don’t even have to set my alarm. I wake up before it goes off, and it keeps getting earlier. This morning, I woke up at 6:45. I have lost the ability to sleep in, even on the weekends. Some days I will have a nap in the evening, for a couple of hours, if I need it. Otherwise, I go to bed by 1:30 and still wake up before 8.
Damn.
I was a night owl as a teenager and college student. Then, along about when I turned thirty, something changed and I became constitutionally incapable of staying up all night.
So I’m an early bird. I love those first couple of hours (coffee, first dibs on the newspaper, a walk by the ocean), so much that I even get up at 5:30 on weekends.
Now I’m pretty much useless after about 11.
Fully night owl here and always have been. I love the night, although I do like seeing the dawn just before going to bed.
