I used to have trouble falling asleep because of sleep anxiety. Fortunately, I learned some ways that help: 1) Eliminate pressure to fall asleep- let go of fear and regrets of not getting enough sleep. 2) Understand that even if you don’t actually sleep, you can still gain “rest” while awake by being physicall and mentally relaxed which will recuperate energy equivalent to some sleep. 3) Use conventional mind relaxing techniques like counting backwards, counting sheep, or listening to music. These techniques may not work for everyone. 4) If conventional mind relaxation techniques don't work for you, try meditating- using various techniques such as being a passive-observer of your thoughts and images you see OR focusing on one particular thought that's positive or relaxing, OR unforcefully think of no thoughts at all. 5) Don't get tempted to get up for anything, and eliminate all potential temptations in advanced. 6) Take sleeping pills (these help ALOT)! ! 7) Wear earplugs, and keep an extra set near you incase one falls out during sleep.
go to bed earlier and get up earlier then your required "wake up" time. 9) Go to bed at a regular routine. 10) Use your bed only for sleeping and nothing else. 11) Don't eat, exercise, or consume any caffeine before going to bed. I hope you find these helpful. If you have any other tips/suggestions, please share!
