... 300mg, however this gave me priapism, so dropped the dose immediately to 150mg to which I have been on now for 8 years. I have always felt groggy in the morning, but sleep is immediate and sound. I desperately want to get off it. I have had nights off trazodone and feel alive the next day, in-spite of horrendous vivid dreams and experiencing more of a nap than a good nights sleep. I have tried to cut down slowly, but the withdrawal is awful. Could someone please advise me as to how long the withdrawal effects last before I can expect to feel me again?
