I was diagnosed with Idiopathic SFN 15 years ago, Civilian Doctors were of no help, wasted 12 years on Gabapentin which only made me sleep most of my life away. Forced into retirement I qualified for VA and the Veterans Hospital has been a God send. I can now afford Pregablin that helps so much more than Gabapentin did, I have been using Alpha Lipoic Acid and it adds to relieving sensations. I do suggest trying it. Every Body is different so listen to your body and don't discount prayer it has helped me more than anyone. God Bless
