(Blood Alcohol Concentration). One long-neck bottle leaves the bloodstream of a 70kg/155lb male individual in little less than two hours. He'd be just renovating the same content of alcohol over and over (and have the night to rest). And, during his initial intake, he'd have a 0.028% BAC, which, according to a table in the same site, means: "average individual appears normal".
EDIT: corrected the BAC for a 70kg male individual.
