At the best of times, alcohol makes us feel great — relaxed and gregarious, warm and fuzzy, happy and confident. But at the worst of times, it can morph into a serious problem, damaging our relationships, our health, and our lives as a whole. On this encore episode, we explore our relationship with alcohol. Why we consume it, how it affects us, and when it’s time to quit.

We talk with surgeon and recovering alcoholic Charles Knowles about how booze affects our brains and health, and what finally pushed him to give up alcohol for good; we hear about a trend known as “California sober,” and why so many people are embracing it; and we find out how zero-proof cocktail bars are helping some people socialize without the booze.
