Which of the following restores sobriety in someone who has been drinking alcohol?

The only way to restore sobriety in someone who has been drinking alcohol is to wait until they alcohol leaves their system

• either by way of metabolism or by excretion.

There are a few ways to speed up the process (but it still takes time).

Drinking lots of water will slightly speed up the process of excreting the alcohol.

Eating may provide food to soak up some of the alcohol that is still in the stomach before it enters the bloodstream, lessening the length of time a person stays drunk.

Vomiting up the alcohol in your stomach will also lessen the time it takes to become sober again.

In extreme cases of alcohol poisoning it may be necessary to do blood replacement - drain the alcohol containing blood while replacing it with alcohol-free blood. It won't sober them up it will speed up their recovery.
