Ozzy Osbourne says Sharon Osbourne suffered "Exorcist"-like seizures during her treatment for cancer.
The Black Sabbath rocker has confessed he was terrified of losing his loyal wife, Sharon Osbourne, when she was diagnosed with colon cancer in 2002 because she often suffered violent seizures.
"She had three chemotherapies a month and after nine months the side-effects got worse and worse.
"She was having seizures - she was like The Exorcist, bouncing around the bed. I thought I was going to lose her."
Ozzy also shared his anxiety about losing Sharon.
"She is the strongest woman I know. When I saw the scans of the colon, I thought, 'No way'. The cancer was so aggressive.
"I thought it was all going to be too much for her. Then at the end of the nine months the doctor said, 'She's going to need nine months to get over the chemotherapy'. Her response was, I'm cancer free, great. I'm going shopping."
The Black Sabbath front man also opened up about his struggle with alcoholism.
"I go to AA [Alcoholics Anonymous] meetings at a place close by every lunchtime. I didn't want to but I had to if I wanted to keep my family.
"It's hard. I had a therapist at first but that didn't work so I agreed to try AA."
Ozzy - who is now 19 months sober - added: "Alcoholism is an illness. I don't like going to the meetings but if I don't go I know I will drink again. And I worry about losing everything, so I just don't want to drink anymore."
