This book is for the millions of struggling patients who have, through no fault of their own, become unusually sensitive to the normal stimuli of light, sound, touch, food, chemicals, and EMF, such that they can no longer tolerate those stimuli without significant suffering . . . This book will bring a new understanding of the neurology, physiology, and biochemistry of what creates this kind of sensitivity, and the medical conditions that are most likely to set it off. Even more important, it lists the many new approaches to reducing and curing these sensitivities, based on newly obtained knowledge.
