Amy Winehouse's family said that she died from alcohol withdrawal, the Sun reported Thursday.  The family went on to say that her sudden abstinence killed her.  London Ambulance Service received a call at 3.54pm Saturday.   When they arrived there, the woman was already dead. A spokeswoman for the London Ambulance Service said, "Sadly the patient had died."

Police await toxicology results that could take up to four weeks.

Winehouse's family said that her small body could not handle such profound change and that she died from a seizure.  Family sources told the newspaper that the "Rehab" singer, who was found dead aged 27 on Saturday, was killed after ignoring her doctor's advice to cut down on her heavy drinking gradually.

A source close to Amy's family told the Sun, "Abstinence gave her body such a fright they thought it was eventually the cause of her death." 

At Winehouse's funeral, her father Mitch Winehouse, denied reports that she went on a 72-hour binge. 

A rabbi led the service and prayers were recited in Hebrew and English. Winehouse's father, jazz singer Mitch Winehouse, who instilled in her a love of music from an early age, said in a eulogy, "Goodnight, my angel, sleep tight. Mummy and Daddy love you ever so much."
