LATEST: Robbie Williams checked himself into rehab to kick a staggering daily drug intake including three packets of cigarettes, 36 double espresso coffees, anti-depressants and sleeping pills, according to reports. A British newspaper claims the singer became hooked on caffeine, nicotine and Seroxat before seeking help at the Cottonwood Clinic in Arizona. But The Sun alleges Williams has not lapsed in his longterm battles with alcohol and cocaine. The newspaper writes, "The singer finds it impossible to get to sleep until 4 or 5am due to insomnia and is on sleeping pills. He is hooked on the powerful anti-depressant Seroxat, which has been linked to suicidal tendencies in teenagers. "And daily he gets through an incredible 36 super-strength double espresso coffees, 60 Silk Cut cigarettes and around 20 cans of energy drink Red Bull."
