Yes, I've beenon it for about a year and half now. It was prescribed by my Endocrinologist for my PN. The PN flare ups that I used to get were quite painful, severe, deblitating, and frequent (once every 4-6 weeks; over 4-5). Mainly in my feet and sometimes my hands. After taking EB-N5 about a month or so noticed the attacks weren't as severe and didn't last as long. Fast forward a a little over a year now. I may go 2-3 months and experience some minor tingling that is absolutely tolerable compared to what I was experiencing before starting on EB-N5. This is phenomenal considering that I used to take Lyrica 100mg three times a day with minimal, brief relief. I use a little cold therapy (ice pack) now to help with the minor flare ups and that gets me through with ease. I pray this is helpful and you have a great outcome as well. All the best to you!
