My doctor put me on Cymbalta for Fibromyalgia. I did not have the best reaction to it. I was ill for several weeks, had dizziness, and was sweating like I was in sauna. While I was on it, I was a bit odd. Someone told me that their loved one died, and I flippantly said "Oh, well that is too bad". While my intention was to show compassion and sympathy, it was almost like being slighlty drunk all the time and I felt I was acting slightly off. I also have a hard time remembering stuff while I was on the cymbalta.
As to the fibromyalgia, it helped with the pain reduction for a bit, but then it started to magnify the pain....it was weird. That is, of course, irrelavant for your use of cymbalta.
Tapering off the Cymbalta was miserable for me. I had the head womps, dizziness, nausea, shakes, sweats, increased pain and it took much longer than I expected.
With all that said, remember that people are more apt to document the negative than the positive. Cymbalta may very well work for you but you do not know until you try it. Discuss it with your doctor. It is ok to talk about it. All medications have the potential for side effects. I do know that St Johns Wort acts simularly to Cymbalta, and some have been able to use it without the onslaught of side effects other than having to stay out of the sun. However, I really recomend you discuss that with you psychiatrist before self medicating.
What ever you choose to do, I wish you the best. You are ultimately in control and the choices are yours.
