insomnia
"I have been taking 10 mg of Ambien for about 4 months and I want to get off of it so my doctor recommended that I try trazodone instead.  I tried 200 mg of trazodone without the Ambien and I had a horrible night.  It took over 3 hours to fall asleep and when I did finally get to sleep, I had horrible nightmares.  Since then, I have been taking 5 mg of Ambien along with 100 mg of trazodone and it has been all right.  I go right to sleep, I sleep all night, and I only have a few vivid dreams.  I want to wean myself off Ambien completely so it will just take some time."
