Cymbalta does have withdrawl effects. I would talk to your doctor. I tried to do it myself and had loud bells ringing in my ears when I looked suddenly one way or another. My doctor backed my script down from 60 to a low dose I was to say 25 or something, not sure but it was about half and I took it for 2 weeks straight then she reduced it to 1 every other day for 2 weeks, still felt funny for about 3 additional weeks. I will not go back on it. I honestly didn't feel it did anything for me and it was one less pill that I didn't have to take.
