"i have been diagnosed with idiopathic hyper insomnia, my mind does not shut off at night. i have been prescribed 100 mg of trazadone to sleep. let me tell you!! i fall asleep with in a couple minutes and sleep all night, waking up refreshed. lately though, i can sleep like a rock and still very tired through the day. i am wondering if maybe its from prolonged use. i cant even imagine sleeping with out it!"
