My doctor proscribed Hidroxicina (half of 25mg tablet) to help me sleep. It works well with no unpleasant side effects. While not unpleasant it does produce the effect of very vivd dreams. I wonder if anyone else has experienced this with this drug.
I did once have weird dreams that I almost have never had otherwise and ascribed them to a pill (not a sleeping pill); the doctor took me off of them, and those dreams stopped.
