I attended a talk by a doctor discussing neuropathy last week. She said Lyrica was an update of Neurontin, with less of Neurontin's side effects. Neurontin is also known as gabapentin. The doctor said Neurontin's most-often complained about side effect is that it makes people feel like zombies. (Not the technical term.

)
As for taking them together, she didn't mention it.
