Are you running to the liquor store to keep warm this winter? Don’t worry, you’re not the only one. With shorter days, longer nights, chilly temperatures, and extended vacations, why wouldn’t winter be the ideal time of year to sit back with your favorite alcoholic beverage and drink your way through family gatherings? Data released by BACtrack, a company marketing breathalyzers that connect to smartphones, has revealed the top 15 drunkest days of 2013, and winter holidays did not disappoint.
