Comedian Billy Connolly has stopped taking his medication for Parkinson's disease because they were apparently turning him into a sex addict.
He told a chat show in the US that the side effects are an overriding interest in sex and gambling, the Mirror reported.
Scientists say drugs used to treat the neurological condition are linked to compulsive shopping, cleaning and gambling, as well as a higher sex drive.
Billy was diagnosed with the degenerative brain disorder last year after an Australian doctor, who was a fan, told him he was showing early signs of the illness.
The star - who is married to psychologist Pamela Stephenson, 64, and has five children from his two marriages - also had prostate cancer surgery before getting the all-clear in December.
