Sleep Hygiene
It all starts with Scheduling, and don't add coffee.
Most people can get good sleep regularly with some basic lifestyle changes. We're not re-inventing the wheel!
To get you started, remember:
Plan regular sleep and wake time. Allow 8-9 hours for adults, more for teens.
Turn off electronics 2 hours before bed, at least for visual use. Do something relaxing instead.
If at all possible, use your bedroom (or at least your bed) for sleep and sex only.
Avoid coffee / tea from afternoon onwards, depending on your response to it.
Don't eat a big meal or exercise right before bed. Do exercise 30-90mins 5 times per week.
If you snore, are overweight, or wake up tired, get checked out for sleep apnea (Resource below).
