Don't listen to an inasurance agent. I'm an in surance agent, no way someone other than your dr. should advise you.
I was on Gapapentin (PCP) and went to 300 mg and only gained 25 pounds. No help.
Ahead 2 yurs. My NEUROLIGIST ordered Cymbalta 60mg. 50% better with PN. Also my joints feel much better.
