A German court has ruled hangovers are an 'illness'.
It comes after a case was taken against a company, that was selling drinks it claimed could cure a hangover.
In its ruling, the court said no food or drink product can market itself as being able to cure or relieve an illness.
It explained an illness includes "even small or temporary disruptions to the normal state or normal activity of the body".
The court confirmed that also applies to the tiredness, nausea and headaches commonly associated with hangovers.
The decision comes just days after 'Oktoberfest', a month long beer festival, began in Munich.
