Treatments for diabetic peripheral neuropathy and ways to reduce some of the pain?

I suffer from diabetic peripheral neuropathy and the pain is unbearable at times. I have been on Gabapentin to treat the pain but with it I have gained 30 pounds. Is there anything else out there to help reduce the pain? Or any OTC medicines or at home remedies? Thank You So Much! http://bit.ly/o5bbOv
