Cymbalta Review

I have taken prescriptions for bipolar disorder for many years..My Dr. suggested I try Cymbalta due to the fact it helps with aches and pains and I have degenerative arthritis. This sounded like a good idea until I became very unstable and had to come off Cymbalta and resume a more traditional prescription.I have never had this kind of reaction with any other bipolar drug. I do however realize everyone reacts differently..
