When he first appeared on the show one year ago, Survivor: China winner Todd Herzog was battling an alcohol addiction so severe, his family feared he could die at any moment. A clearly intoxicated Todd received a dose of reality from Dr. Phil and agreed to enter a 90-day rehab program. Several months later, in February 2014, Todd took part in Dr. Phil's 2000th episode and had a happy update: He had been sober for 112 days. But Todd’s mother, Shirley, and stepdad, Chuck, say Todd has since fallen off the wagon completely and is now worse than ever.
