Can't sleep ?

I often feel too wired up to get a good night's sleep .
Sleep deprivation and kid's sickness aside
So I try to remember these simple steps.

1. A nightly routine ...and like the kids stick to it
2. Reduce alcohol consumption (not that I drink much) 
3. Avoid caffeine and a heavy meal or snack before bedtime
4. Light exercise in the early evening helps you sleep deeper
5. Warm bath or shower if you prefer
6. Make a list for tomorrow ... but no thinking , worrying or excessive planning
7. Temperate even room temperature ...more than 18 ° but less then 30 °
8. Dark & quiet room  (earplugs if necessary)
9.  Journaling or discussing what is worrying you with your spouse
10. Set a bedtime and stick to it ...

What else do you do to develop good sleep habits without drugs ?
