According to Amy Winehouse's family, booze didn't kill the singer: The lack of booze did. Family sources tell the Sun they believe she cut herself off from alcohol too quickly, giving her body a fatal "shock." Doctors had warned her to quit drinking gradually, but instead she went cold turkey three weeks before her death. "Abstinence gave her body such a fright they thought it was eventually the cause of her death," one source says.
But, the Sun adds, Winehouse may have fallen off the wagon three days before her death: A source saw her drinking gin and Red Bull at a London music festival. But her mother and boyfriend saw her the day before her death and were convinced she hadn't been drinking. Click for more on the unreleased music Winehouse reportedly left behind.
