I think ypu should change how you spend your day. Proper body and mind conditioning is essential to achieving a healthy sleep pattern. Here are my suggestions
1. Avoid caffeine intake mid day to night. Caffeine is a stimulant.
2. Avoid exercise 2-3 hours before going to sleep. Adrenaline is released during exercise.
3. Read a good book before going to sleep
4. Use bed only to sleep.
5. Dim of turn off the lights in your room.
