If I turn out the light at the time I'm supposed to be asleep, I'll lie there 30 min to an hour, especially if I've had the tv or light on.
I'm really guilty of getting sucked into a baseball game and having to turn it off.
So, go to bed at the same time.
Get up at the same time( I havent used an alarm clock in 35 years and I never overslept for work even once. I wont be able to sleep knowing a loud annoying sound will occur at some point in my sleep----sleep has been much more restful for me because of that---body clock is on point)
Don't drink caffeine after 2
Don't nap after 2. When you're tired at that time, do something active or fun if you're able too.
No bright clocks in the room.
Exercise in the morning. I run a mile everyday and walk another mile or so.
Eat healthy
Dont eat right before bed
Have a prayer time( or meditation) I do mine during my run in the morning. (Its before sunrise and no one is on the roads)
I hope this helps someone!
