ROBBIE WILLIAMS IN ARIZONA MEADOWS

Robbie Williams is hooked on anti-depressants Seroxat and Xanax, and the painkiller Vicodin, it has been reported.The singer - who checked himself into a rehab clinic yesterday, thought to be Arizona's Meadows centre - also gets through 36 superength double espresso coffees, 20 cans of Red Bull and 60 cigarettes every day, according to reports.The troubled star - who quit alcohol and cocaine six years ago - is also reportedly battling insomnia and has been taking strong sleeping pills. Robbie recently told Britain's The Sun newspaper : "I can't honestly say that I don't take too many prescription drugs. How many is too many? If you drink as much coffee as I do, you easily get into the too-many-sleeping tablets thing."I hate drugs, I love drugs. As depressing and heartbreaking as it is, it makes life interesting."Robbie's fears of becoming addicted to prescription drugs were apparent in the lyrics of 'Good Doctor' - which features on latest album 'Rudebox'.The lyrics read: "I've got all these demons and I can't stop them. To tell you the truth, Doc, I might have a problem."Robbie was reportedly plunged into depression after his former band TakeThat eclipsed his own album and 'Close Encounters' world tour with their reunion shows and hit LP.Their comeback single 'Patience' topped the British charts and has been nominated for the British Single BRIT Award . For the first time in a decade, Robbie isn't in the running for a major prize at the BRITs - which takes place in London tonight. Meanwhile, Robbie's mom Jan says checking into rehab on his 33rd birthday was the "best gift he could have given himself". Jan, a drugs counsellor, said: "I have known about Robbie's problems for some time. It has been very worrying. I will be going to see him soon."
