I'd like to suggest that you ask your doctor about METANX and cymbalta.

Metanx has helped someone very dear to me tremendously. It is a vitamin combination. Cymbalta is also said to help with neuropathy and has also helped my friend.
This METANX is something else! A lot of docs are not even aware of it so take some info in with you.
