Has anyone had any success taking Cymbalta for peripheral neuropathy? If so, how long did it take before you noticed any relief?

I have idiopathic peripheral neuropathy if I should ask my neurologist about Cymbalta. I have already tried gabapentin and oxycarbazepine without success.

Just curious with others' might have experienced with Cymbalta. The PN is relentless, the tingling nerves feel like they hit me down to my core. It's unbearable and is making me depressed as well.
