A hangover is a collection of signs and symptoms linked to a recent bout of heavy drinking. The sufferer typically has a headache, feels sick, dizzy, sleepy, confused and thirsty. Generally, IV drips were only been offered to sick people. Ultimately many symptoms of a hangover are related to dehydration. About a liter of liquid is injected into the blood stream via a needle to take from hanging. IV drips are been used in some countries to treat hangover. However this is not advisable.
