As I mentioned in reply to your last post, stress-reduction during waking hours, wind down time before bed are both important preludes to quality sleep. But most important is setting a regular sleep wake schedule, meaning arising at close to the same time every day, including weekends! Getting outside first thing after awakening (within 1/2 hr or so) gives a strong signal to your circadian clock when morning is, and also sets the melatonin timer to return approximately 16 hrs later to make you sleepy at bedtime.
