As a treatment professional, I consider Never Enough by Dr. Judith Grisel to be the single most important book I have ever read on addiction and the biology of the brain. Dr. Grisel, a neuroscientist and former addict herself, masterfully explains how substances alter brain chemistry, disrupt reward pathways, and reshape behavior. Her unique blend of personal experience and scientific expertise provides profound insight into why recovery requires both biological healing and behavioral change. This book bridges the gap between neuroscience and compassion โ a must-read for anyone working in or affected by the field of addiction.
