Like "I agree with knowledge is power. When I first got sick. It was bad I couldn't even walk to the bathroom by myself. Thanks mom. I went three months being tested for MS. Because my doctor was clueless to my symptoms I have now figured out that my d and b-12 was the cause of my nuropathy. I had no idea that b-12 plays such an added roll in our bodies. If left untreated it's deadly. It also causes memory loss alztemiers ect. In the book the first year type two d. By Gretchen Becker it goes into great detail. I gave this book to my d friends mom and close friends for Christmas. So they can learn more for them selves and to know what I am going through. "
