Answer:
Once ethanol is in the circulation, it reaches all tissues in the body, including the brain, where it causes intoxication. Our bodies are designed to terminate the action of drugs, including alcohol, so that the intoxication doesn’t persist when a person stops drinking. In fact, the body starts eliminating ethanol before it even gets into the general circulation!
Explanation:
Between 90% and 98% of all alcohol that enters the body is metabolized and absorbed. The remaining alcohol is excreted through sweat, urine, vomit, and feces. It takes one hour for each unit of alcohol to leave your body - this means if you had eight pints of ordinary strength beer and stopped drinking at midnight, all of the alcohol would not be dispelled from you body (and you would not be safe to drive) until about 4 pm the following day.
Throwing up after drinking may reduce stomach pain that the alcohol has caused. If a person throws up shortly after having a drink, the body may not have absorbed the alcohol, potentially lessening its effects
