Has anyone found a treatment that helps with peripheral neuropathy?

I found one that completely got rid of my peripheral neuropathy while on it, but I'm not advising anyone to try it. It was serendipitous. A friend of mine at work mentioned that he took lithium to help with his ADD/ADHD. He and I are very similar in our ways and I thought that I would give it a try. I did not have a prescription for his lithium medication type, and knowing that it's an element, searched Amazon.com to see if there was a supplement available. I found one called lithium orolate and the reviews were positive from it helping mood, anxiety, etc., so I thought I'd give it a try. I took the 5mg dosage and by the second day, my PN was gone. It had blocked it better than gabapentin and THC/CBD prescribed by my pain Dr. Now the side effects because there is no free lunch, right? I lost most of my sense of taste and had to urinate a lot more often. I stopped taking it and my PN is back and my sense of taste is slowly coming back. I didn't see any comments in the reviews about people losing their sense of taste and after an AI search believe that my system is hyper sensitive to lithium. Others in the comment section said they had been taking it for years with no side effects. Anyway, I'm not suggesting anyone take it, but I am here to say it helped my PN better than anything I've taken yet.

@levelup I suspect u r a senior. Nerves need vitamin B12 to maintain their insulation. B12 is extracted from foods that contain it in our stomach acid. Because us seniors have less stomach acid we have less B12 circulating. Those of us who eat plenty of B12 rich foods like liver ,mussels, don't loose their nerves insulation. METHYLCOBALAMIN is the best supplement.
COBA stands for cobalamin. That's a soil mineral that's supports B12 making bacteria. Wind blows it onto grass and we eat the animals.
That's why vegans have to take a supplement. Go for it. Eat better food.

@jamessaxo yes, I'm 59, and you were right about the B12, the problem I had was that I had TOO much via B12 injections, plus, I wasn't watching the B12 I was getting in supplements (more on that further down in this paragraph). My B12 levels were 5x the safe upper limit when I finally had them tested and could have been higher than that, sadly. So, I'm now on the slow recovery phase which could take 6 months to a year. Pins and needles coupled with burning sensations when exposed to heat sources like sunlight, warm temps outside of air conditioned buildings, and the rise in blood pressure from anything like laughter to anger to fright triggers it. But I believe that it's getting better, however slowly. To your point, there is literature everywhere about the lack of B12 and neuropathy, but also misleading information everywhere that says that your system "gets rid of excess B12". This is correct, it does, but first (as you probably know since you are knowledgeable about B12) it's stored in the liver for later use. The lithium orolate worked as a nerve block for me, but losing much of my sense of taste was a bit harrowing.

I take a B12 injection once monthly. Is that enough? Also I eat sugar. I a pre-diabetic with a Hgb A1C of 5.9. Could the sugar be affecting my feet?
