Daniel Radcliffe, who stars as Harry Potter in one of the most successful film series of all time, has opened up in a new interview with GQ in which he reveals that he has struggled with alcohol, including drinking a lot on the set of the 2009 movie “Harry Potter and the Half-Blood Prince,” MTV.com reports.

Radcliffe also reveals that he became caught up in the Hollywood lifestyle, but found that it wasn’t a good fit.

"There were a few years there when I was just so enamored with the idea of living some sort of famous person’s lifestyle that really isn’t suited to me," Radcliffe said. He added that he decided to clean up his act last year while filling the final “Harry Potter” installments.

"There’s no shame in enjoying a quiet life. And that’s been the realization of the past few years for me," Radcliffe said. "As much as I would love to be a person that goes to parties and has a couple of drinks and has a nice time, that doesn’t work for me.”

Referring to his past drinking, Radcliffe added: "I really got away with that because there were many instances when a paparazzi shot like that could have been taken."
