If heavy drinking follows a period of moderate drinking,people may poison themselves with an overdose because the moderate drinking

A) stimulates their secretion of serotonin.
B) reduces their body's level of free radicals.
C) depresses their vomiting response.
D) increases their inhibitions.

Moderate drinking can reduce the body's tolerance to alcohol and depress the vomiting response, making it more likely for someone to drink to the point of alcohol poisoning if they suddenly binge drink. This is because the body has not built up a tolerance to the higher doses of alcohol, and the vomiting reflex is depressed, making it harder for the body to expel the excess alcohol.
