sedation
"I've used Phenergan, which is sold over the counter, as a sleeping aid for about one year now. Taken one hour before bedtime, it rarely fails to put me to sleep. The wondrous thing is that I have kept the same dose, and there are no withdrawal symptoms, if you stop using the drug for a week or two. Definitely the best substitute for any prescription sleep aid, that I've ever tried. Highly recommended as a sleep aid."
