Hangover

A hangover (veisalgia) describes the sum of unpleasant physiological effects following heavy consumption of drugs and liquor, particularly alcoholic beverages. The most commonly reported characteristics of a hangover include headache, nausea, sensitivity to light and noise, lethargy, depression and thirst.
Hypoglycemia, dehydration, Acetaldehyde intoxication, and vitamin B12 deficiency are all theorized causes of hangover symptoms. Hangovers usually last 1 to 4 hours,although some have been reported to last two or three days after alcohol was last consumed
