I took Cymbalta for about a year and a half starting at 10 mg and increasing to 60 hoping that it would help with my back pain. When it didn’t, I then decided to wean myself off. While I took it, it caused Gastro problems. Getting off of it was horrible. I realize now that it was helping with the small aches and pains, but the Gastro side effects and the withdrawal I would never wanna go through again.
