If you keep a journal and decide to quit something, you can make an entry and guage your symptoms, pain,anxiety, etc. If you come off two things at once or don't allow sufficient time in between then confusion reigns. I stopped Gaba and titrated down for about two weeks. I had increased pain and thought that I had misjudged the Gaba. I stuck with the abandonment anyway and no longer take it. The increase in pain seemed to be short lived or I bacame used to it. Most here titrate down as some people have a bad time withdrawing some not so much. From the posts I remember, Cymbalta is rough. I had a sketchy 36 hrs when I quit Hydrocodone. You have to, often times,decide if the side effects are worth the relief you get. Good Luck, Ken in Texas.
