Multiple causes ….and perhaps you need to experiment with a few
Perhaps the hardest being if you are stressed and worrying about something.
As said, if you stress about sleeping that itself becomes another stress….so looking at the alarm clock/phone is bad…
Just get up for an hour… or two and get “stuff done” accept it..
Go to bed later but set the alarm when you need to be up and just force it for 1-2 weeks.
TBH I almost came on at 3am to post on this thread but then I just watched some Netflix for an hour…
At the moment I know that work stress is the biggest cause but I’ve also had times when it’s just patterns because I’ve been working shifts or going to bed early…
The only common thing is worrying about it never helps… only makes it worse.
