I dream constantly every night, the curtian moving in the room could wake me and I have fibromyalgia. Ambien (regular) works wonders for me for about 4 hours. I'm out. Sleep wake rested...just don't know what to do with the rest of my night. Puts my fibromyalgia into remission. I tried CR to see if I could get 8 hours of sleep. OMG, the 4 days I took it around 10pm..up at 7a but I don't remember anything until about 10a and parts of my day after were missing. Drowsy all day, irritable. NO MORE CR.
