First high-dose Vitamin D book by a patient who was also a doctor

The pain doctor had not known about the power of Vitamin D Because of a serious accident, he became a patient He discovered Vitamin D and greatly improved his health with high-dose vitamin D He then went on to prescribe 30,000 IU of Vitamin D to >2,000 patients His very well-written book includes many success stories with sleep problems, weight problems (both loss and gain), pain, and flu. I have read and reviewed virtually every major vitamin D book written in the past decade. This book is in the top 3 of more than 30 books.
