Under the Influence

(Original airdate: January 23, 2012) Kelli admits to drinking and driving on a regular basis and says she’s tired of being lectured about it. On a typical night out, the 40-year-old mother of two admits she’ll consume as many as 13 beers before driving home, but says her high tolerance for alcohol allows her to drive safely. Watch what happens when Kelli is put to the test! Then, Sarah, 30, says she didn’t think that she had a problem with alcohol, until she took an exit ramp at 72 mph and crash-landed upside down on a guard rail -- while driving under the influence. Initially given a zero-percent chance of survival, Sarah spent 77 days in the hospital and has since endured more than 44 surgeries, including two facial reconstructions.
