The clinical symptoms and manifestations of sleepiness are usually caused when the human body consumes too much alcohol, which is rapidly absorbed by the mucous membrane of the gastrointestinal tract and decomposed into acetaldehyde under the action of ethanol dehydrogenase in the liver, at which time the human body enters three periods: first, the euphoric period; second, the ataxic period; and third, the coma and lethargy period. Usually, when the body enters the first two phases, it rapidly enters the third phase, that is, the coma and drowsiness phase, when it feels weak and has the clinical symptoms of sleepiness. Therefore, the human body’s reaction after drinking is from excitement to inhibition, so the final reaction after drinking is sleepiness, and the body is sore and weak, the mind is not clear, the consciousness is gradually lost, the consciousness is unclear, and the reaction is poor.
