(Cover) - EN Showbiz - Amy Winehouse's family reportedly believe the singer died due to her body not being able to handle withdrawal symptoms from alcohol.

Family sources have told British newspaper The Sun that Amy ignored her doctor's advice to cut down on her heavy drinking gradually.

They believe she died from a seizure due to her tiny body not being able to handle the shock of a drastically reduced intake of liquor.

Amy, who had a highly-publicised battle with alcohol and drug addiction, spent a week in a rehabilitation centre earlier this year and her father Mitch said he believed she was on the road to recovery. During his eulogy at her funeral Mitch revealed she hadn't drunk for three weeks before her death.

"Abstinence gave her body such a fright they thought it was eventually the cause of her death," the source said.

The Back to Black singer was found dead on Saturday aged 27 in her North London home.

"[Mitch] said doctors had told Amy to gradually reduce her intake of alcohol and to avoid bingeing at all costs. Amy told him she couldn't do that. It was all or nothing and she gave up completely," the insider added.

"Mitch said the shock of giving up, after everything she had been through over a bad few years, was just too much for her to take."

The post mortem carried out on Amy's body was deemed inconclusive with toxicology test results expected in a few weeks which will determine the cause of death. (C) Cover Media
