I'm okay with 6 consistently, although I find that it's easier for me to go with an irregular sleep schedule and jump between 4 and 8 hours as needed. I don't start feeling extra sleepy unless I sleep less than 6 hours for several weeks. I used to think I had really bad insomnia as a kid since I was expected to sleep 8-9 hours and frequently didn't fall asleep until two or three in the morning.

Interesting, I used to have insomnia as a kid, and I've come to realize it's because I wasn't tired at bedtime. I seem to have a 28-34 hour circadian rhythm if I naturally let it go without trying to force it back in to 24 hours.

I haven't ever thought about a circadian rhythm. It's honestly pretty irregular for me, though I can basically just sleep whenever I want to.

Yeah the circadian thing took me until I was like 22 to figure out. I just notice that I keep going to bed later, and later and later... until one day I just get no sleep, or I double-sleep, and then it re-aligns things and I'm back to going to bed at 11am instead of 6am. But it's always drifting like that, it puts me on about a 28-34 hour circadian rhythm.
I also have a lot of "momentum", waking up takes a while, as does falling asleep.

I've honestly never experienced anything like that. I usually just have a set sleep schedule though, to try to use my time well (then watch videos online for two hours after I wake up super early, negating the purpose of the entire routine). That's kinda cool.

Yeah it's cool most of the time with the longer waking periods as I can get a lot done. But it sucks when you wake up at 6 in the evening and the whole waking period it's dark outside, and you just basically have to wait a few days for your rhythm to realign to daytime lol

Do you not have any control over it?

I have some control over it, but I can never stresslessly conform to the 24h rhythm for months on end. It's always a struggle tbh

Sounds rough. I didn't know this was a thing... ! I don't think I have any actual restrictions on when / how I sleep - I don't get jet lag or anything.

I don't get jet lag either haha. I didn't know it was a thing either until it happened to me, basically. And I've read studies that in the dark, without any day/night cues, most people will naturally fall in to a 25h rhythm, longer than 24. Which is interesting. I'm just kind of an extreme case of that, I guess.
