Give me a night or two of good sleep...and I won't be tired until 1am. Waking up for work will then be hell (I don't function well on low sleep).
My body knows when it is tired...but that doesn't match the work schedule :( When I'm practicing sleep diligence (which comes and goes based on whether I've been tired a lot lately or not) I have to force myself to go to bed when I'm not feeling tired. That feeling of sacrificing time is almost as hard to maintain as being constantly fatigued.
First world problems, but they are my problems.
I have a lot of issues with this (my circadian rhythm delay is pretty bad). My employer tolerates me coming in at 10am but even then I'm still suffering symptoms of sleep deprivation pretty constantly and don't feel like I can survive without sleeping in to midday on Saturdays and Sundays...
It's a frustrating condition to have, because while research into circadian rhythms has generally found that you can't fight against your natural sleep cycle long-term without experiencing sleep deprivation, pretty much everyone who has a normal cycle will tell you that you just have to "be more disiplined", "just wake up the same time every day and you'll get into a better routine", etc. Even most GPs I've talked to aren't up-to-date with the latest research and it's been really hard to convince them to refer me to a sleep specialist! It's also especially bad at work, because management tend to be older (sleep cycles are usually at peak delay during adolescence, and then shift earlier as you age) and seem to have an impressive ability to not understand the condition. But if the science is to be believed, what people tell me is about as effective as telling a severely clinically depressed person to "just be happier."
But even for people with more normal (average) cycles, one sleep scientist has suggested [1] that work shouldn't start until 10am, which would make people more productive and more alert.

I feel your pain. Been there many times. The way I solved it was to become the boss.
Daywalkers will never understand. Even if you're an owl rather than a lark it's looked down upon - and the standard trope of "you're just lazy" come out; but delayed sleep phase syndrome where it's possible to go in and out of sync with the day is a real killer for the regular office hours.
I now get significantly more work done than at any time in my career because I sleep and awake when I want. Of course occasionally I need to be in-sync with someone (meetings, etc.). But it's relatively easy to have a few things to get in-sync with if I get good sleep the rest of the time.
I don't think there is any one thing that helped me come out of it either. A few large changes, like a better job, and some moves like limiting caffeine intake after 3PM or so helped. I feel like it's stress, plus being a night owl to begin with, and maybe a light sleeper as well.
Using f.lux, exercising, no caffeine past 5 and establishing proper sleep hygiene fixed it for me, but it took me till my 30s to figure it out. Drinking alcohol seems to be very expensive on sleep cycles. With exercise I also found I needed to do it before 8pm or I would often still be very awake. The other thing is meditation to calm yourself down, I found that sometimes I would be breathing very fast when lying in bed, turns out I was wired still.
And when I slip, I'm back to finding it harder to get to bed on time, 12:30, 1am, 1:30am, 2am, problems start with getting to work on time. Having to catch up at the weekends, sleeping till 12. Finding it incredibly hard to get going on Mondays.
I also found when I had slipped with correct bedtime, melatonin helped me reset my sleep clock back to midnight. Taking it just one or two nights 45 mins before bedtime, will help me get back to bed at a right time. Apparantly the standard dose is 10x what you actually need (300 micro-g is enough, rather than 300 mg). I only use it once every few months.
I've heard that as it wears off there's a "rebound" effect, so that alcohol now means being more wakeful X hours later. I've never really been (or wanted to be) drunk enough to know for sure.
Seriously, part of the reason you're probably not tired is because you simply have not done enough physical exertion.
But then again, I'm fairly active at work (have to go up and down stairs between my office and the lab dozens of times a day, standing lab work, walking out to the warehouse to get parts, etc. which actually adds up to quite a lot, even if it's not very strenuous) so maybe if I just sat at a desk all day it would be a lot worse.
having kids basically just makes life impossible and painful.
Buying a kettle bell or stationary bike and doing HIIT can wear you out in <20 minutes.
On weekends I ski moguls for 6+ hours in the winter and hike 12ish miles in the summer.
The only time I feel a lack of energy is when I _stop_ regularly working out. You can be very efficient and get the same effect doing 20 minutes of HIIT. When the weather is marginal or I just don't have time that is what I do.
So perhaps your natural rhythm is very late night bedtime and late morning wake time? Does make life in the standard 8-5 world difficult unfortunately.

I work from home and I have a lot of flexibility since I live in a different timezone from my clients so I make that work but it is frustrating for my wife. Workouts don't really seem to help much, melatonin seems to improve things slightly.
Sometimes my clock gets so out of phase that I'll fall a sleep at around 10AM and sleep until 19PM or so. It's pretty tough to go back to regular schedule after that, heh.
We know that blue light is a strong cue to your brain to keep delaying the clock -- perhaps your brain is unusually sensitive to it.
I do tend to work late at night because of timezone differences between me and my clients.

My experience with flux was that the screen still gave off enough blue light that it didn't make much of a difference for me.
Seems increasingly common with our modern lifestyle.

Low functioning on little sleep, but a good night or two and I'm up at 1am.
Right now, I simply sleep when I'm tired and waking when I please most days. I generally sleep from about 4am to noon, approximately. Additionally, sleeping later in the day produces a better sleep. I sporadically sleep through alarms and loud noises.
It does make the normal 8-5 world more difficult to deal with.
In a nutshell, with a bit of free running sleep you can readjust your cycle.
I guess just listening to what your body is telling you and not pushing it, especially if the reason is work (side-project or career), but even just staying up for something trivial like watching a movie or whatever. Maybe I can use a lack of dreams to tell when I've gone too far.
A serious complication to the variable length of sleep is that when you get a bad back after sitting for 20 years, you can't catch up on sleep anymore as the back hurts after X hours in bed anyway.
One of my benchmarks of my tiredness, and conversely how rested I was, was if I was having dreams. When I was exhausted, sleep would be pure black abyss and the time between sleep and awakening could have been the blink of an eye for all I knew. When I was sleeping reasonably (~6.5+ hours) I would start to dream again after a few days.
I take things a bit easier now, it's much easier to resist distractions like Facebook or the news when I'm rested than when I'm extremely exhausted.
Heavens knows what happens during parenthood and you simply have no choice, presumably there must be some psychological instinct that takes over...
Hah. Haha. Hahahahahhahaa trails off
One of ours woke 4-6+ times per night, every night, for nearly a year straight. It's beyond just "affecting sleep" and well into Gitmo-style sleep deprivation.
After my first kid, I've had no problem at all catching and cherishing a nap. Dreams, I think, are the brains garbage collection mechanism. Without them, the system just grinds to a halt.
Also, having small children affect sleep although not directly, it's the time you try to claw back after putting them to sleep, pushing it a little later to get other things done.
After a while it became obvious nothing much was being achieved this way, in fact my mental acuity seemed to drop substantially.
Then I realized I hadn't been dreaming (or at least remembering dreams) for a while and that was weird. Slowed down, went to bed as soon as tiredness kicked in for a few months. Improved my diet which probably helped a lot.
Dreams have returned with a vengence, it feels like all night is one long dream, I feel better and sharper.
I wish I could sleep less than 7 hours, but my body disagrees.
