I read this book at a friend’s recommendation in 2014 after nearly a decade of frequent episodes of debilitating back pain (also diagnosed as a her herniated disc).
Gave it an honest try because I figured I couldn’t lose- Either at home or I could make fun of my buddy for recommending nonsense.
Genuinely life changing for me.
Ever since, on the rare occasions when it does flare up again I reflect on the ideas from the book and apply them. Works amazingly well.
