According to a report in the Royal Society of Chemistry, the best hangover cure is toast with a large dollop of honey.

(Hangovers are caused when the body converts alcohol into the toxic chemical acetaldehyde.

Other hangover cures exist:  Hair of the dog, a fry-up, and coffee are all popular cures for a New Year’s hangover, and there are lots more disgusting suggestions and concoctions that you can find on the net, but a plate of toast and honey provides the body with the sodium, potassium and fructose it needs.”  The report added that the best way to avoid a hangover in the first place is to have a glass of milk before you start drinking, stick to gin or vodka with a few soft drinks throughout the night, and then have a pint of water before you go to bed, but let’s be honest, the best way to avoid a hangover is to not get drunk in the first place.)
