I'm 80 years old and have suffered with Chronic Idiopathic Polyneuropathy (CIP) for 30 years. I believe in and have adopted a strict plant based diet, but my symptoms didn't improve until I got some help from my PCP. Researchers have found no cause of CIP but have found it gets worse with age. Oh great! My PCP prescribed high doses of Gabapenti and a psychiatrist put me on Remeron to help me sleep at night and Xanax. It has been a godsend when it goes crazy throughout my body. I rarely take more than one mg a day. I also found a Chinese herb called Corydalis to be helpful.
