Hangovers occur when you drink too much. A hangover’s symptoms include nausea, headache, fatigue, dry mouth, and much more, depending on the individual. The specific cause of hangovers remains a subject of intense medical debate, but the presumed causes include dehydration, buildup of chemicals like acetaldehyde and other toxic compounds, and the inclusion of congeners and histamines in wine and spirits. Genetics and individual tolerance are also major factors, as different people react differently to alcohol consumption.

Since 2015 this category has largely been deprecated at Drinkhacker and we no longer actively cover hangover cures or preventatives.
