I've been sleeping like a rock all through the night with my meds since Sept 6th: Ambien, Trazodone, and Prazosin. Prazosin is very helpful for nightmares. Ambien helps me fall asleep, and Trazodone helps me stay asleep.
During the day I am still tired, but if I take a nap then I'm flooded with nightmares. If I stay awake then I live with flashbacks and dissociation.
