I have neuropathy and I can attest to the fact, that for some people, it does cause tiredness. Every day, along about one to two pm, I give in to it and have myself a lovely nap. It works for me and I don’t worry about losing sleep at night from it. Your body heals when it is resting so that’s how I justify my afternoon naps! Hope you feel better when you read this! Hugs and all the best.
