Alcoholics are being warned to go slow when trying to quit drinking following reports Amy Winehouse died after ignoring her doctor's advice not to go cold turkey.

Britain's Sun tabloid is citing family sources as saying the 27-year-old "Rehab" singer suffered a fatal seizure brought on by a sudden, three-week abstinence from booze.

The report says the singer's family believes her tiny frame could not cope with the loss of alcohol in her veins after many years of binge drinking.

Canadian addiction specialists confirm going from heavy drinking to nothing can be lethal.

Rob Hadley of the Vancouver Addiction Centre says the body develops a level of chemical requirement and if it's not met, it literally goes into shock.

Hadley says quitting requires addicts to get treatment from professionals that will reduce dependency without risking their health.

Daniel Jordan of the Sunshine Coast Health Centre says alcohol is one of the most dangerous drugs to detox from.

He says the chance of dying from a withdrawal from alcohol is actually much more than for heroin.
