Hello and welcome to Dream Views.

I took melatonin before and it doesn't do anything good for me. I now only take it when I'm in dire need of deep sleep.

Other sleeping aids I took before I joined this site, one med perscribed by my doc, did nothing but offer dreamless sleep and left me still feeling drowsy in the mornings.

I think almost any sleeping aid will have some sort of effect on your dreams one way or another.
