This week the tough questions come from Greg's Twitter followers. What would they ask one of the top epilepsy doctors in the world? Their questions and Dr. Joe Sirven of the Mayo Clinic's answers will surprise you.

They tackle the differences between brand and generic medicines, holistic approaches to treatment, and what everyone should know about some of the most difficult aspects of epilepsy, such as SUDEP (Sudden Unexpected Death In Epilepsy).

Greg and Joe have a history you're going to have hear to believe. Greg's recent appearance on Joe's podcast and NPR radio show: "What's Health Got to Do with It?" wasn't enough. Listen now. (Available wherever you find your favorite podcasts, like this one.)

Talk About It with Greg Grunberg is sponsored by Greenwich Biosciences, the US leader in the field of cannabinoid prescription medicines.
