Things I've been trying to consistently do in order to improve my sleep:

• Stop drinking alcohol
• Brush my teeth immediately after dinner
• Don't eat anything after dinner
• Wear my mouth night guard
• Drink decaffeinated coffee, regardless of time of day
• Run every morning
• Spend at least 45 mins outside each day
• Wake up when my body tells me its time to
• Black out any lights in the bedroom

It's a work in progress.
