Here's another thing to add to my nightly ritual: nose strips.
I forgot about them because I think that (strangely enough) I did not use them last winter. I did search through my grocery receipts (they are electronic) and the last order I have for them is in 2021. So I think my memory is correct.
I tend to use them when the temperature turns colder. I restarted using them last night, and it made a difference in my sleep. I still woke up a bit early, but I slept very solidly prior to that.
I'm now wondering what the experience of other autistic people with these might be.
