What is a good med for peripheral neuropathy? I can't take Gabapentin.

Not major problem. Many choices including Lyrica (which may be tolerated better than gabapentin, but also consider Horizant and Gralise). Might try Cymbalta, Savella, (milnacipran) amitryptyline, but may benefit from lamotrigine, levetiracetam, other tricyclics or even SSNRI's. But maybe find etiology of neuropathy and treat cause directly.
