How long does withdrawal from trazodone last?

How long do I have to suffer from withdrawal from trazodone cold turkey?

I was taken off 50mg Trazadone I was taking by my sleep Dr cold turkey and for a month I never slept more then 3 hours a night I am back on it again. I wish I was not but it is I guess safer then regular sleep meds for long term use. (I have found it makes my eyes blood shot too which is a bother) But I do sleep again thankfully
