According to Sharon's interview with ABC's Barbara Walters, to be aired on the network's 20/20, she demanded that Ozzy stop his own alcohol and drug abuse while Jack was waiting to check in to the clinic, but he refused. She then left for a few days and only returned when Ozzy proved he was serious about stopping his drinking and drugging (or, at least, proved he was as serious as Ozzy is capable of being in his current condition).
Why tell this story now? Well, Sharon's new daytime TV talk show is scheduled to debut this week, and rumors have been flying that the show may be a disaster. However, it's difficult to believe that the most-public and most-publicized family in America had a "real" split that no one heard about.
