Four and a half years ago, podcast producer (and Big Kate's boyfriend) Derek finally did something bad enough to quit drinking for good. This week, he joins the Kates to discuss his greatest hits and lowlights, how sobriety helped him evolve as a person, how he started drinking, how sobriety has made him a better father, and how he got sobriety to stick this time. BONUS: why does he like the Kates so much? Follow Derek on Instagram at @van_sober.
