In the book, "Wheat Belly," by William Davis, M.D., a cardiologist from Milwaukee, Dr. Davis talks about p.n. and its connection to ataxia. He devotes an entire sub-paragraph to the subject and ends by stating that the p.n. will not improve until you give up the wheat and gluten. He talks mostly about diabetics.

I'm not a diabetic but have stopped eating wheat to see if it helps. That's not easy to do as wheat is in everything these days. He has studied wheat from its beginning, and noted how it has changed over the years and recently in our attempt to grow a product quickly that will feed the world.
