Scientists identify four drunk personality types

The menacing Mr Hyde drunks, named after the sinister alter-ego of Dr Jekyll in Robert Louis Stevenson's 1886 novella, should be avoided at all costs. These are the hostile types who become more disagreeable with every drink and are most likely to experience blackouts or be arrested for drunk and disorderly behaviour. Psychologists found that two thirds of the people in this category were women. The study was published in the Addiction Research and Theory journal.
