Answer:
When an individual takes moderate concentrations of alcohol gradually, the alcohol generates a mild-up feeling known as the good buzz. However, a point comes known as the point of diminishing returns, that is, the BAC becomes more than 0.6, at this point, the buzz will not get better with more drinks.
In reality, consuming more alcohol at this stage can result in more negative feelings, such as fatigue. This up feeling succeeded by a down feeling if one drinks too much has been illustrated as the biphasic response to alcohol.
