Dear Dr. SerVaas: My husband had numbness and needles-and-pins sensations in both feet. Podiatrists and chiropodists defined this to be (an unknown cause) neuropathy. He suffered with this for over two years. I read an article to him about not using NutraSweet. He'd been drinking Crystal Lite as his preferred beverage. When he discontinued this practice, voilą--no more neuropathy. It's 100 percent gone.

Dear Dr. SerVaas: I believe that Berber carpet caused my peripheral neuropathy (and my dad's, and my dog's). When I discovered that and covered my carpet with cotton and nylon rugs, my feet improved 99 percent. My dad and my dog felt better.
