You've probably heard I didn't know I was pregnant stories that went something like this: A woman claims she took an at-home pregnancy test that came back negative, but, lo and behold, she really was pregnant -- and the pregnancy progressed without her knowledge.
Carbonation in anything you drink allows it to enter the bloodstream faster. There is no difference with an alcoholic beverage. If you drink alcohol that is either carbonated or mixed with a carbonated beverage, then it will absorb into the bloodstream faster than drinks that are not carbonated. Examples are cocktails such as Jack and Coke, which is whiskey mixed with Coca-Cola.
How does alcohol move through the body? Once swallowed, a drink enters the stomach and small intestine, where small blood vessels carry it to the bloodstream. Approximately 20% of alcohol is absorbed through the stomach and most of the remaining 80% is absorbed through the small intestine. Alcohol is metabolized by the liver, where enzymes break down the alcohol. In general, the liver can process one ounce of liquor (or one standard drink) in one hour. If you consume more than this, your system becomes saturated, and the additional alcohol will accumulate in the blood and body tissues until it can be metabolized.
