i went off the gabapentin and on to lyrica. the lyrica works so much better, with no side effects and i works. i was taking 3 high dose meds for my fibromyalgia and sleeplessness and went on 100mg 2xday of lyrica and been fine.. no side effects at all. i even lost some weight with it. a few people i know that take it are fine with it too. so i don't know it is different for everyone
