Robbie Williams has become dependent on the medication he takes to help himself cope with depression, because he feels "suicidal" when he stops taking the pills. The former "Take That" star has struggled with alcohol and drug abuse, and famously battled an addiction to painkillers including Vicodin during the mid-2000s.
He managed to get clean after checking into The Meadows rehabilitation treatment centre in Arizona on his 33rd birthday in 2007, but he admits he's still hooked on anti-depressants, and he's terrified of giving them up.
He says, "You get suicidal when you come off them (anti-depressants). There's a buzzing, and weird things start happening. It's very scary."
