Troubled singer AMY WINEHOUSE has vowed to follow the advice of her hit song REHAB and never go back to a treatment facility, despite her recent alleged drug problems. The 23-year-old is currently taking time out of her pop career to focus on "health issues" following her hospitalisation last month (Aug07) after three days of hard-partying. But, during a surprise appearance at Tuesday (04Sep07) night's Mercury Music Prize awards ceremony in London, Winehouse declared she has no intention of seeking expert medical treatment to combat addiction again. Speaking to British newspaper the Daily Mirror, she said, "I'm of the school of thought where, if you can't sort something out for yourself, no one can help you. Rehab is great for some people but not others." She added, "Normal people spend time thinking, 'What am I going to do with my life?' I spend my time drinking."
