LOS ANGELES: Oscar winning actor-director George Clooney wants to give up partying because he hates hangovers.

Clooney turns down party invitations because he has realised he has to take care of himself after he had neck surgery in 2005, reports imdb.com.

The Syriana star says, “I don’t live at full tilt the way I used to. You begin to hate waking up with the kind of hangover you get from going on huge benders with your buddies. Also, since my neck surgery, I’ve been forced to take things easier and not beat up my body the way I used to. I’m more tious.”
