Query: a cautionary tale

I read this book soon after I started seeing Dr Hedaya for depression. There are some useful nuggets in the book about the benefits of good nutrition, regular exercise, and meditation. However, after following Hedaya's treatment plan to the letter for almost two years - including a regime of up to 30 supplements a day and various diets - and spending over $40,000 on appointments - he charges $400 per 50-minute appointment - and expensive lab tests, I got no results. His so-called integrative holistic approach ('whole psychiatry'), which is supposed to reduce a patient's dependence on medications, had me increasing the number of medications I was on, including an anti-convulsant. His claim to be able to restore a patient's vital biological factors and hormonal balance through nutritional supplements and special diets has not been supported by the available scientific evidence. If you do read the book, I recommend getting a second opinion before acting on its recommendations.
