I took 200 mg of Trazodone for sleep for less than 6 months and weaned off by lowering the dose by 25-50 mg for two weeks at a time. But my sleep issues started again so now I'm taking 50-75/mg a night for sleep. Call your pharmacist, mine gave me advise on how to taper off. He said the longer you are on it, the longer it takes to taper off and 6 months was considered a fairly short time. There are several websites with helpful advice, if you search.
