Is there a sleep aid without diphenhydramine?

Melatonin: My first suggestion is to practice good sleep hygiene -- keep your sleep structured, use bed for sleep and intimacy only, avoid lying in bed long periods, avoid day time napping. Melatonin is a naturally occurring hormone and over-the-counter supplement that can help improve sleep if taken at bedtime. It is not, and does not contain diphenhydramine. Give yourself 6-8 hours to sleep. Good luck!
