According to IMDB, Clooney, 45, has decided to stop going to parties because he hates feeling hung over the following day.
The star of the film Ocean’s Thirteen has been attending a fewer number of social functions since making his decision. The lifestyle change also comes after Clooney underwent back surgery in 2005. The actor explained, "You begin to hate waking up with the kind of hangover you get from going on huge benders with your buddies. I’m more cautious."
