Feeling like a drunken rat? Have a tot of 'cuddle hormone'

We all know the feeling, huddled in the corner, wishing the room would stop spinning after having had one too many, while more sober friends continue to party.

But scientists believe they may have found the answer.

Researchers from the University of Sydney have found that a dose of the "cuddle hormone" oxytocin sobers up intoxicated laboratory rats who quickly regain their concentration and coordination.

"In the rat sobriety test, the rats given alcohol and oxytocin passed with flying colours, while those given alcohol without oxytocin were seriously impaired," said Dr Michael Bowen.

The researchers demonstrated that the hormone prevents alcohol from accessing specific sites in the brain that cause alcohol's intoxicating effects, sites known as delta-subunit GABAA receptors.

This "sobering-up" effect of oxytocin has yet to be shown in humans. And it's worth noting that oxytocin will not save you from being arrested while driving home from the pub.
