I stopped taking lyrica because of the weight gain. Today, my doctor put me on neurontin. If others have made this switch, could you please tell me if you got the same pain relief as with lyrica? In addition to lower back pain and a recent L5/S1 ALIF, I have fibromyalgia. The pain has prevented me from being able to do any exercise, including walking on land, and in the pool. Your thoughts would be appreciated.
