Some people aren’t capable of identifying when they’ve had enough to drink. Consequently, they drink way too much.

A UC Santa Barbara study found a brain mechanism that senses the negative effects of alcohol, like headaches and dizziness. It alerts us to these effects and helps to control the urge to drink.

When it doesn’t function properly, we can’t tell when we’ve had enough. Consequently, we continue drinking.

This research says some people aren’t made aware of the intoxicating effects of alcohol. As a result, they drink more than they should.
