... was helping me. I was taking 3200mgs a day then down to 2400mgs for a month, now its 1600mgs a day. I feel every nerve in my body. It's a struggle everyday. The Cymbalta she put me on makes me dizzy, spots in front of my eyes, blurred vision. I want to go back to taking the dose of gabapentin that was working. Can my doctor say NO to me going back to my 3200mgs that was working?
