Will you vomit if you drink a gallon of milk in one hour?

Drinking a gallon of milk in one hour can lead to nausea and vomiting for many people due to lactose intolerance or the sheer volume of liquid. The stomach can only hold a limited amount of food and liquid, and consuming too much at once can trigger the body’s gag reflex. Individual tolerance varies, so while some may vomit, others might not, but it's generally not advisable to attempt this.
