One day I went without and could feel a real difference. My numbness was more pronounced. You do need to use it up past your ankle to get it to start working. I would feel more tingling in my arch and feet when I did that. The paperwork suggests that tingling means it is working. I am deciding whether I should order another bottle. There is nothing else out there that has done anything for me. The secret ingredient is listed as JC7. It is made up of three substances that are not listed. If anyone knows of anything that works really well, please post.

Thanks,

Sherri
