insomnia
"Was really disappointed. I started at 10mg (have taken Ambien IR 10mg for 2yrs). It actually worked great - maybe the first sleep aid that made me feel genuinely, naturally sleepy, not drugged and sedated. But after I went to sleep, I had 3 hrs of horrible, vivid nightmares that woke me up every 5 minutes panting & sweating. I also experienced sleep paralysis for the first time in my life. It was absolutely terrifying. I tried to keep at it for a few nights as several people have said the side effects go away quickly, and even tried only taking 5mg, but it was intolerable. Too bad. It is maybe worth noting that I take a handful of other meds including Seroquel, Klonopin, Lamictal, etc."
