Insomnia
"I have taken trazodone off and on for about five years. As long as I&#039;m taking it every night it works just fine, but if I skip a night I won&#039;t sleep at all. No physical dependence, but if I&#039;ve been taking it regularly and then stop I can&#039;t sleep more than an hour a night for at least a week. Works well when taken nightly, but has a horrible rebound effect."
