My wife took 100 mg Trazadone every night before bed as a sleeping aid, an off label use. I tried it myself and it didn't work as a sleep aid. I was also looking form help with stress caused depression, it didn't seem to help me in that area either. I switched to Sertraline (Zoloft) not sure if that will help with depression or not.
I find the generic Ambien doesn't help me sleep either.
