Winehouse 'replaced drugs with alcohol' prior to death, says friend

Amy Winehouse had "replaced drugs with alcohol" prior to her death.

The 'Rehab' singer - who was found dead in her home in Camden, north London, on July 23 at the age of 27 - "lost track of days" after drinking herself into oblivion at her flat because she was "bored" and couldn't go out anywhere for fear the paparazzi would stalk her.
