CBC's "The Nature of Things" ran a documentary about the nursery last year.

Growing up in the Maritimes of Canada, I was introduced to a simular drink in college. It was formally called a Red Eye, but we also called them Seizures (a play on Caesar). It was 1 part Beer and 1 part Tomato Juice.

Tomato Juice contains fructose, a type of sugar that helps your body metabolize alcohol more quickly which helps prevents hangovers and is a hangover cure.
