I have told my current pdoc. He just laughs at me. Actually he laughs at more for a lot of different reasons. Needless to say I am looking for another. I am currently weening myself off of Cymbalta. Can not stand the side effects.
Only advice I have is that it is your body, you know what you are feeling. If your pdoc won't work with you then it's time to get a new one. I say this eventhough I haven't accomplished it yet.

Work in progress.
