My Dr. has recently taken me off from my Soma and put me on Zanaflex. I can't understand why. She told me that it was because Zanaflex is not a Controlled Substance and that Soma is. Now she has increased my Cymbalta to 2x a day. Can someonetell me what is ging on with this? These are both substances used to treat Depression. How can they possibly treat the muscle spasms I have I my back and neck.
