No. Don’t rely on the “rule” of one drink an hour. Generally, one drink should be absorbed and eliminated from the human body in one hour. Nonetheless, more than one client of mine has reported that this “rule” was followed before being arrested for a DUI. In reality, alcohol metabolism is a complex process that is dependent on many variables, such as gender, body weight, body hydration, and food content in the stomach. Other factors, such as recent gastric bypass surgery and certain diets, will unexpectedly increase a person’s BAC (blood alcohol concentration).
