Have you taken it before? I personally hate the stuff...I tried it in the psych ward to help sleep and for anxiety and it just makes me feel weird and irritable. Not sure what effect that med would have on nightmares....I take trazodone to help sleep(not every night though) and it does certainly get me to sleep but yeah doesn't help my dreams much. Sometimes I try and avoid sleep to avoid disturbing dreams but I know its not healthy to go without enough sleep to.
