It's pretty much the same for me other then with Neurontin I had really bad brain fog and with Lyrica I really, really sleepy all the time. Not tired, just sleepy. I was on Neurontin for 6 or 7 years and I don't think it case damage but really how can I judge that. LOL I like Lyrica much, much better. Why? It works for me! Neurontin did nothing really, just took the edge off. Probably because I of the brain fog.
