Final answer:
To sober up after drinking, the only cure is to give the liver enough time to metabolize the alcohol.
Step-by-step explanation:
The only effective way to sober up after drinking is to give the liver enough time to fully metabolize the alcohol. Drinking coffee or taking a shower will not help with sobriety. It takes at least five hours for a legally intoxicated person to achieve sobriety as the liver metabolizes alcohol and excretes it.
