There is no consensus definition of veisalgia ("alcohol hangover," from the Norwegian kveis, or "uneasiness following debauchery," and the Greek algia, or "pain"). Most descriptive and experimental studies have identified a set of common symptoms: headache, diarrhea, anorexia, tremulousness, fatigue, and nausea [ … ] . Perhaps the most alarming feature of veisalgia is its high prevalence. In a study of college students, 25% of students reported experiencing a hangover in the previous week and 29% reported losing school time for hangover recovery.
