Hi Julie, Welcome to HealthcareMagic Forum.
He is indeed suffering from Alcohol Intoxication
which is the consequence of drinking large amounts of alcohol in a short period of time. Drinking too much too quickly can affect breathing, heart rate
, cause nausea and vomiting. He needs immediate medical attention as he is losing body fluids, call for emergency medical help
right away. Until the help arrives keep him sit up and try to keep him awake to prevent loss of consciousness
