My Psych started me on cymbalta friday ... and I was wondering if its one of those that takes a month before it levels you out or if it works right away ???

I have been all over the place since ... i was wondering if I could expect this for a while or what ??? I appreciate any input (i know i should have asked my dr, or he should have told me what to expect ... I think ... neither of us are worth a crap ??
