My doctor has had me on Trazadone for 5yrs now, for the fact that I can not sleep and please trust me on this, I was a Correctional Officer in a level 3-4 Prison and my father was dying of Parkinsons Disease so therefore I quit the prison to take care of him he recently passed away on june 6, 09 but I was taking Trazadone when they gave me a urine screen and a mouth swab and it does not show up as anythng at all! THIS WAS A STATE PRISON SO IF IT SHOWED UP AS ANYTHING THEY WOULD OF SENT ME PACKIN OUT THE DOOR AS QUICK AS I CAME IN!!!!
