I take Melatonin 6 mg tabs every night to sleep one half hour before bedtime. Helps me tremendously. Knocks me right out. Also, exercise every day. That helps too. I do yoga every night about one or two hours before bed. Helps calm me before bed. That's my exercise. I also do mindfulness meditation for 15 minutes twice a day, everyday. That helps with sleep too. I also keep my thermostat turned down at night to 72 degrees. I never have a problem with sleep now. I used to have terrible insomnia.
