A Quitting Smoking Emergency

Tony struggles with identifying a support system—friends who he can talk to when crisis hits. He tells Dr. Oz that he's really isolated. "I really don't have any friends outside of my wife," he says. "I work with people, and I come home and spend time with my wife and kids."

When Tony quit drinking years ago, he says he lost contact with most of his old friends and now devotes himself to Wendie and Bailie. But that leaves him emotionally exposed. "My biggest fear is losing my wife and my daughter," he says.
