Dr. Teitelbaum, I'm writing this email to express my deepest gratitude to you for your work and the book you wrote, From Fatigued to Fantastic! In 2008 when I found your book in the bookstore, it was like a godsend. I had been suffering for many years with long-term fatigue, short-term memory loss, anxiety and other problems. I went to both allopathic and naturopathic doctors and they all told me the same thing, they couldn't find anything diagnostically wrong with me. I was healthy and fit but I just felt awful. I even had a doctor tell me I should begin an exercise program. When I explained that I was now tired all the time and in the past had been a dedicated exercise enthusiast working out 5-6 times a week for at least an hour, I got a blank look. It was then that I realized that I would have to figure out my own way back to wellness.

If you take a look at the scientific literature on iodine, and you’ll see frequent reports about the risk of hyperthyroidism from a too-high intake of iodine. This problem is relatively rare, and just about the opposite of what’s actually happening in the U.S. — an epidemic of hypothyroidism, with a widespread deficiency of iodine playing an important role.

Though opiates are sometimes needed for pain control, they can cause a myriad of problems, including hormonal dysfunction. In addition to the commonly known side effects of narcotic medications, there are many lesser-recognized side effects. One is a deficiency of B-vitamins, which might show itself as "perleche" — inflammation at the corners of your mouth (the right and left ends of your lips). The problem (also called angular stomatitis, and sometimes caused by Candida) usually resolves with antifungals and a B complex supplement.

In this study, involving 266 women with constipation, eating yogurt containing active probiotics and fructooligosaccharides (FOS) was found to reduce constipation relative to a milk-based dessert without probiotics. While on the yogurt (Dannon's Activia), people had an average of 6 bowel movements a week vs. 5 a week while on the dessert.
