I was put on trazodone 150mg for sleep about ten years ago. It worked pretty well and no side effects, so I stayed on it. As I got older it started to have an effect on my bladder control. I only had this problem about an hour after taking it, so I know it was the culprit. Anyway, I decided it was time to get off it and found out the hard way you have to wean off this med, low and slow. I have been cutting down by 25 mg every couple of months and am now down to 50 MG, ready to drop to 25. Like any med, I suppose your withdrawal will depend on the dose and length of time you've been taking it. Best of luck.
