All hangover cures therefore only work because they address these problems in some way. Coke or other soft drinks work because their water content helps to rehydrate the body and due to their high sugar content that replaces the lost glucose/sugar. (People tend to prefer drinking them flat though as the absence of bubbles is often kinder on a hungover stomach.) Greasy food such as fried bacon and sausages works not because of the fat, but because of the high salt content that is usually present in fatty foods. Coffee only appears to work as the caffeine acts as a temporary stimulant, it is best avoided though as caffeine itself has to be broken down by the body like alcohol does and therefore causes further dehydration and actually makes matters worse.
The most effective cure is to concentrate on what the body is missing and therefore drink water with sugar and salt dissolved in it. Something I learned from a a group of medical students many years ago was that you can often avoid a hangover completely if before bed you drink two pints of water with a table spoon of sugar and a teaspoon of table salt dissolved in each.

Unconscious drunks that are taken into A&E on a Friday & Saturday night are usually treated with10% glucose solution (sugar dissolved in water) and 0.9% saline solution (salt dissolved in water) that is put directly into their blood stream via a drip. You would be amazed at how much better they look in the morning compared to their mates who have been sitting in the A&E waiting room drinking coffee all night!
