"hi. i got some of this from my doc as i was having bad dreams about my father who had recently passed. my experience has been absolutely awful. dreams out of this world! it takes the first 2 hours of the day getting over the wild vivid craziness that happened in your supposed deep sleep. then came the depression!!  i have never been depressed and never full understood how others felt, now i do!!  i knew it was the melatonin so i stopped and i was fine. i am not going to ramble on but be so careful, it&#039;s an insidious drug, for me anyway."
