The 26-year-old actor gave up alcohol after he finished filming 2011's "Harry Potter and the Deathly Hallows Part 2" because his drinking was getting out of control and says working out helped him to stay sober, reported Female First.

"Like the cliché of anybody who is quitting something, I really got into exercise," he said.

Radcliffe admitted drinking to excess and having to be looked after by friends on more than one occasion.

"I can't tell you what kind of drunk I am because I don't remember what kind of drunk I am. I think I'm probably great - while I'm conscious. But then I have to be looked after and ultimately I don't want to wake up to 20 text messages along the lines of, 'Where are you? Dude, are you OK?'" he said.

"I change when I'm drunk. I'm one of those people who changes. There is something in any person who drinks in a way that's clearly not good for them, something that is attracted to that chaos."
