insomnia
"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's an insidious drug, for me anyway."
