Write a how-to guide for me detailing how I can get more restful and better sleep. Include only 3 different overall tip categories.
How to get better, more restful sleep:
1. Keep a sleep schedule - Make sure you set aside no more than 8 hours for sleeping. The recommended amount of sleep you should get, for a healthy adult, is at least 7 hours per day. Try to get up at the same set time every day of the week, as having a consistent sleep pattern 
    re-inforces your body's natural sleep-wake cycle. Furthermore, if you aren't able to fall asleep within 20 minutes, leave your room and do something relaxing, like listening to soothing music. Do this until you find yourself getting tired.

2. Be aware of what you eat and drink before bed - Don't go to bed hungry or overly full. Avoid having heavy or large amounts of food for at least a couple of hours before trying to sleep. Nicotine, alcohol, and caffeine are things you should be cautious about as well. Nicotine 
    and caffeine are stimulating, and the effects of that can take hours to wear off, which interferes with your sleep.

3. Make a restful environment for sleeping - Keep where you sleep cool, quiet, and dark. Exposing yourself to light before resting makes it more challenging to sleep, and bright screens should be avoided before bedtime. Consider using tools like earplugs, a fan, or room- 
    darkening window shades to create a more restful sleep environment.
