What affects the amount of alcohol in your blood?

Alcohol is absorbed into the bloodstream through the stomach walls and the intestines as a person drinks. A loss of inhibitions is sometimes one of the first effects. As more alcohol is consumed the BAC rises. However the exact time that the body takes to absorb alcohol varies from one person to another. A number of different factors affect your BAC, such as how much have you eaten; what time of day it is; your mood; your metabolism; your fatigue levels – all these things count.
