My doctor prescribed it for my neuropathy, I remember trying to take it in the past and having trouble but I thought I'd try again for him. I also take Tramodol for pain but doc cut me way back on that, thus my problem. I have Hep c, cirrosis, heart disease, diabetes, CAD< PAD, neuropathy, and I suspect either fibro or arthitis, I still go to work everyday so I need to be alert. My tramodol was working just fine for ten years but then got a doc who wanted to mess with things!
