Why do only some drinkers become drunks?

 Our complicated relationship with alcohol goes far beyond Dry January. Dr. Charles Knowles is professor of surgery at Queen Mary University of London, chief academic officer at the Cleveland Clinic London and a consultant colorectal surgeon. He joins host Krys Boyd to discuss his own problem drinking and the steps he took to finally stop, what science says about addiction, and how we can reset our own relationships with alcohol. His book is “Why We Drink Too Much: The Impact of Alcohol on Our Bodies and Culture.”
