Treating a hangover with more alcohol, on the theory that denial is medicine.

means Having a drink to cure the hangover that drinking gave you, on the folk logic that the cause can also be the cure.

from Short for 'hair of the dog that bit you,' an old folk remedy belief that a wound from a (possibly rabid) dog bite could be healed by placing hairs from that same dog on it. The phrase jumped from literal folk medicine to drinking culture by the 16th century, used figuratively for curing one ill with a small dose of the thing that caused it — alcohol included.
