I have been on Cymbalta for nearly a year now. For me, it has helped, though not at much as I had hoped. I do like the anti-depressant properties of it though.
I did notice a BIG change in my outlook on life and things that would have made me sad (like when I can't do things I want because of my pain) don't make me as sad anymore.
The only side effect I've noticed is on occasion it feels as if I've got fireworks in my head. Strange descript
ion but the best I can give. LOL It isn't daily, and the only time I notice it is when I haven't taken my pain meds.
If you're comfortable making a change, go for it!
I hope it works well for you too!
