[They say i have diabetic PN but I'm sure its Idiopathic PN. Anyway I have been taking Metanx for 2 months now and I see no change. The brochure says it can take up to 4 months to see a difference. I hope so. The metanx can be compared to taking 19-1mg folic acid tablets, 2-B12-1mg tablet and 2-B6 25mg tablets. Only good thing is Ins. covers it I'm hoping it will work.
