Thanks for the suggestion. I haven't had caffeine in decades, but that was a good idea to check.
In my case, it just seems to be an issue getting off the computer rather than getting to sleep. I'm asleep within 10 seconds of my head hitting the pillow. It's just getting it there!😂
@Blort It's all about building a habit. Make it your goal to keep your bedtime for one week - no matter what. After a week it will be much easier and after a month you'll have it habituated.
I once automated my lamp to turn off at 23:00 but I just found myself turning it back on 😂
