A week in Italy wrecked Robert Downey, JR's bid to quit smoking and now he's furiously chewing on Nicorette gum in a bid to give up cigarettes for good.
The Iron Man star, a former drug addict, chose to turn his back on his final vice over 18 months ago - but he wasn't strong enough to cope with a promotional trip to Europe.
He tells Playboy magazine, "I almost didn't (smoke) and then I was like, 'This is crazy. Are you kidding me?' But I think the next time I can handle Europe... Cigarettes were just killing me."
