This is a variable thing. The more alcohol that is consumed, the longer it takes for it to be eliminated from the body. To be on the safe side, 24 hours should elapse (even though several hours is long enough in most instance of light drinking, where one or two drinks are consumed.). It takes longer for women to eliminate alcohol, in general (than men), and 50% of the Asian population (in the world) have very little to no alcohol dehydrogenase enzyme, with which to eliminate alcohol - so this is yet another variable.
The only way to remove alcohol from the body is to stay hydrated and wait. Everyone's body metabolizes alcohol at a different rate. The rate at which alcohol is eliminated from the body depends on how often you drink, how much you weigh, and your gender. There are blood alcohol content (BAC) calculators online that can roughly estimate how long it will take your body to process an amount of alcohol. Roughly .015 to .020 grams per deciliter are processed per hour. Don't drink excessive amounts of water as this won't increase the elimination rate of alcohol but keep hydrated to stay healthy.
How long it will take for you to pass a Breathalyzer test after drinking alcohol, will depend on how much you drank. Alcohol is metabolized in the body at a rate of .015 of blood alcohol concentration per hour.
Alcohol effects a breathalyzer test immediately after consumption.

About .015 of BAC per hour.
Generally, there is some affect within the hour.
If by 14 drinks you mean 14 units of alcohol - then the body processes 1 unit every hour thus it would take 14-15 hours for you to be free from the alcohol.
