I have a very hard time going to bed every night. It normally takes at least an hour until I can actually fall asleep. I took ZzzQuil about ten minutes before I got into bed and was fully asleep within 15 minutes! It was wonderful! I've tried Melatonin, I was waking up with several nightmares a night. Then groggy in the morning. I'll definitely always choose ZzzQuil from now on!
