@2dogman welcome! I also have severe polyneuropathy. My neurologist gave me Gabapentin, but I could not stand the fatigue, and dizziness so I don’t take it.
I do not tolerate most pain relievers other than Tylenol. Even that makes me sleepy! So, I grin and bear my discomfort.
I’m glad you are having success with your meditation. That’s important for you ability to get a good nights sleep!
