No.9 - Bill Werbeniuk: Hardly a health role model, the Canadian's heavy drinking became the stuff of folklore. At his last professional match, Werbeniuk said: "I've had 24 pints of extra strong lager and eight double vodkas and I'm still not drunk." He generally drank six pints before a match and then a pint a frame. He was later given medication to curb his drinking, but the substance he took was illegal in snooker and that effectively ended his playing days. He died in 2003 of heart failure just six days after his 56th birthday.
