As a non-morning person, waking up before 8AM usually ensures that I am absolutely dog tired by mid afternoon (~2-3PM) and completely non-productive from 5PM onward.
Waking up at 4AM would mean that time-frame moves up another 3 hours and I would have to finish doing everything I need to during the day by 2-3PM and most jobs would generally look down upon that.
> YMMV of course, but getting up really early might not be as outlandish as it sounds.
Doing it once or twice isn't especially difficult or outlandish, but I haven't managed to keep it up longer than a week despite my best efforts. And it always resulted in absolutely miserable afternoons.
I noticed something similar. A few years ago I tried for a few weeks to be in bed early and get up early. The result was that a) I had more trouble falling asleep because the world around me was a lot more active, b) I wouldn't actually be productive earlier than I would had I gotten up at a "normal" time, and c) I would feel miserable starting some time in the afternoon.
When I go to bed late and wake up late, however, there is no such "miserable" time period.
That said, if I go to bed later than 2-3AM, I'll feel tired the next day.
Sleeping 1AM to 9AM has worked fairly well for me thus far and I'm just glad I have a job that allows me to work flex hours.
I have to add that I find lying in bed unable to fall asleep one the most miserable human experiences. I suspect it's what ultimately led to me developing the late night sleeping habit, since if I was unable to fall asleep within 10 minutes, I would get back up and keep reading or doing something until I was more tired.
Waking up at 4AM would mean that time-frame moves up another 3 hours and I would have to finish doing everything I need to during the day by 2-3PM and most jobs would generally look down upon that.
