I had been on Celexa a few years ago and I had annoying side effects-no sex drive, exhausted, nausea-and the doctor suggested Lexapro. He explained that it's like a reverse molecule of the same medication as Celexa so if I have side effects with one, they may be less likely (or different) on the other. I did much better on Lexapro as far as side effects go. You should talk to your doctor again and ask if you might be better off returning to Celexa. I have never been on Cymbalta but I was curious about it. I read up and it sounded like too many side effects for me.
