Sleep schedule

[Nortd]

I'm half asleep and knackered and pondering if others with neurodiversoty really struggle with normal sleep schedules? I've read before about people with asd sometimes having delayed sleep disorder and I feel I relate to that (but never had a sleep clinic). I am happiest going to sleep at 4 in the morning.
Going to bed at a "normal time" I will oversleep and constantly feel groggy during the day until later on at night and if I get on a normal schedule it will only be a couple of days or weeks before I slip off it and back to my night owl routine.

I really struggle to function if I do t go to bed and go to sleep at the same time every night and wake up and get up at the same time.

Just staying up in the living room to watch a film rather than watching in bed will throw me off as I need to be in bed 2 hours before my sleep time. I also need 30-60 mins in bed in the morning before getting up.

This needs to be the same at the weekend.

I really struggle to cope when the clocks change. It takes me weeks to adjust.

I'm the same as the previous poster, I HAVE to go to sleep by midnight or the next day is a write off and everything feels wrong.
My son is like the OP though. He will stay up till 6am at times.

I'm a night owl by nature which worked well for me when I did the nightshift.

Last couple of years I've taken to forcing myself to get up early otherwise I'd be up all night. I have to let the cat outside anyway so it's an incentive to get up.

My usual sleep pattern used to be 3am until around 10am.
