I've been on 120mg of Cymbalta (or Duloxetine as my psyc calls it) for a while now. It's ok, gave me a few good weeks.
Pretty bad side effects if you stop taking it suddenly though. Not looking forward to getting off the stuff.
For me, the positive effects wore off after a couple of months, so now I'm on Cymbalta and Mirtazapine (Remeron) combined. The mixture is pretty grim so far, can't see me sticking with it for much longer.
Sometimes I wonder if psychs really do know what they are doing!
