Neurontin is a seizure medication that is also* used for chronic pain and nerve pain. Lyrica is the basically Neurontin that is effective at a lower dose, if that helps explain it. It works well for a lot of people. It made me *intensely* suicidal after 3 days on the lowest dose, but I have a tendency to get the psychiatric side effects of medications. I didn't know it was used for anxiety. It's sedating - take it at night.
