Has anyone taken trazodone (Desyrel) for insomnia?

As we just started, he wanted to see how things progress with a little bit at a time. Seems legitimate to me. Been on that 1/3rd since Nov. 01 and it's not helped It's given one less hour of sleep than what I usually got with the Zolpidem alone. I ready to tell this to my GP and see what happens.
