Should I ever seek emergency treatment for a hangover?

Hangovers usually resolve on their own, but there are a few symptoms that can crop up after a night of heavy drinking that should be attended to right away. These symptoms include:vomiting that won't go away, seizures, pallor or bluish skin color, low body temperature, slow breathing, and
unconsciousness. Seek emergency care for a person with these symptoms, as they could be signs of alcohol poisoning.
