Using methodology that includes binge drinking, bars per 100,000 residents, beer wine and liquor stores per 100,000 and number of breweries in each state, Business Insider compiled a list of how hungover each state would be after New Years Eve.

Taking it one step further they narrowed it down to the most hungover cities across the nation. With 23 bars per 100,000 people, 20 stores per 100,000 and 2 breweries per 100,000 people coupled with the fact that 16.5% of people admitted to binge drinking, Casper was ranked #2 most hungover city in the nation.

Other western states represented include Montana, Colorado, Nebraska and South Dakota. See the entire list here.
