Final answer:
The effects of alcohol after having several beers can only be reduced by allowing time for the liver to fully metabolize the alcohol. No other actions, such as drinking coffee or taking a shower, will speed up this process.
Step-by-step explanation:
If you have had several beers before driving, the effects of alcohol will be reduced only by giving the liver enough time to fully metabolize the ingested alcohol. This means that the only way to reduce the effects of alcohol is by waiting the necessary amount of time for your body to process and eliminate it.
The effects of alcohol after having several beers can only be reduced by allowing time for the liver to fully metabolize the alcohol. No other actions, such as drinking coffee or taking a shower, will speed up this process.
Neither drinking coffee, taking a shower, nor any other means will expedite this process. Given the rate at which alcohol is metabolized by the liver, approximately one drink per hour, it takes about five hours for a legally intoxicated person to achieve sobriety.
For safety and to avoid legal issues, it is important to not drive under the influence of alcohol.
