What to do to help sleep in general?

Behavior modifying: One place to start is practicing good sleep hygiene. Keep your sleep pattern consistently structured, avoid napping, use bed only for sleep or intimacy, and avoid lying in bed long periods without sleeping. If falling asleep is troublesome because of trouble turning off your thoughts, relaxation and imagery techniques are often helpful. For more help with these make an appointment with a therapist.
