A close friend of Amy Winehouse has claimed the tragic singer had replaced drugs with white wine in recent months. Kristian Marr, a long-term friend of the late star, told the Mail on Sunday: "White wine was her main drink and sometimes she would wake up and drink. "It meant she lost track of days - for Amy there was no day or night, no Monday or Friday. "Three months ago I popped round to her house one afternoon, found her asleep on the kitchen floor and had to help her to bed.
