The experience of a hangover varies between individuals, but, generally it is characterized by headache, fatigue, dizziness, nausea, and dehydration. A hangover can also cause difficulty concentrating, sensitivity to light and noise, thirst, diarrhea, and lethargy. Psychological effects may include feelings of irritable, depressed, or anxious. For some people, just one alcoholic drink can result in a hangover, while others can drink heavily and still not experience a hangover.
