Would you say the EB-N5 helped your neuropathy?

I am not expert for sure. There is much info on website "Understandanding b6 Toxicity" if you can't find it I'll try to post link. I do know that I had feet tingling, feet feeling like I was walking on rocks, heart palpations, blurred vision , ringing in ears and the only abnormal test was b6 was 118 and range 2.1-21. This was from 20mg of b6 taken in melatonin nightly over about 2+ years . My symptoms were ruled idiopathic because my neurologist knew nothing about b6 toxicity. Since stopping b6 and getting b6 to level of 8, heart palpations are gone and blurred vision and ears ringing resolved. Feet are still numb and feel like I'm walking on rocks. According to the website b6 builds up in your body's muscles and tissues partly due to dehydration and this takes a long time to resolve. The fix for this is not difficult but involves very good hydration not just with water but natural electrolytes, no b6 supplements and stick to b6 diet that only provides RDA of b6 and exercise as much as possible. I follow their Facebook group also and have witnessed many getting better who were diagnosed with PN of unknown causes. So I continue to follow the recommendation there bc it's basically healthy anyway and doesn't cost anything. Many in the group did take the P5P you referred to and got toxic that's about all I know.
