Hangover (Hang-over)

A hangover (also spelled “hang over” and “hang-over”) often results from the over-consumption of alcoholic beverages. “Hang over” meaning something “hanging over” or a residual or after-affect is recorded by the Oxford English Dictionary from at least 1894.
 
The alcoholic sense of “hang over” is recorded by at least 1895 and was written as one word by at least 1904.
 
 
Wikipedia: Hangover
A hangover (veisalgia) describes the sum of unpleasant physiological effects following heavy consumption of drugs, particularly alcoholic beverages. The most commonly reported characteristics of a hangover include headache, nausea, sensitivity to light and noise, lethargy, dysphoria, and thirst.

Hypoglycemia, dehydration, acetaldehyde intoxication, and vitamin B12 deficiency are all theorized causes of hangover symptoms. Hangovers may last up to two or three days after alcohol was last consumed. Approximately 25-30% of drinkers may be resistant to hangover symptoms. Some aspects of a hangover are viewed as symptoms of acute ethanol withdrawal, similar to the longer-duration effects of withdrawal from alcoholism, as determined by studying the increases in brain reward thresholds in rats (the amount of current required to receive to electrodes implanted in the lateral hypothalamus) following ethanol injection.
 
Etymology
The term hangover was originally a 19th century expression describing unfinished business—something left over from a meeting—or ‘survival.’ In 1904, the meaning “morning after-effect of drinking too much” first surfaced.
