as someone who has been through it, i once blew a breathalyzer level of .13 like four hours after i drank 1 tall can of malt liquour. i wasnt driving crazy, i literally took a girl and had sex with her behind a supermarket in my car, and the cops thought we were trying to rob the market. i was arrested and refused to take a second breathalyzer test instead got a blood test. after 1 night in jail and months of just constant worrying before my court date, it turned out my blood contained 0.0% alcohol level, and my case was thrown out. breathalyzers are bullshit.
