I was taking 3-4 3 mg. mellies/night. I hadn't taken them in over a year. My days and nights were getting messed up, so I figured why not? They work, fast! Asleep in 30 seconds at 8 p.m. but the nightmares were ridiculous! I am prone to crazy dreams and nightmares...i had probably 4-5 long nightmares. First one was about the end of the world, (getting bombed, shot in the head, dodging airplanes crashing next to me)..the next dream I had blacked out in my dream (at a bar from one drink), and spent the next two dreams trying to figure that one out. Very tiring and disturbing...but I love sleeping...night night
