Be sure to follow the basic rules of good sleep:
Go to bed and get up at the same time every day, allowing for 7 to 9 hours of sleep.
Keep your bedroom dark, quiet, restful, and comfortable.
Limit alcohol and caffeine.
Take time to relax before going to bed.
Exercise daily for at least 20 minutes. Try to finish up at least 4 to 5 hours before you go to bed.
Eat dinner several hours before you hit the pillow.
Switch to decaf drinks and skip alcohol.
Don’t smoke. Nicotine is a stimulant.
