No hangovers in Italy

[tcarlsen]

Cause of Hangover:

According to "The Medical Advisor," a very reputable book I have, "Alcohol by-products called congeners seem to increase the severity of a hangover. Gin and vodka have few congeners and are thus least likely to produce a hangover, whereas brandy, champagne, and whiskey have the potential to cause the worst hangovers. Red wine can also bring on a hangover because it contains tyramine, a substance that can cause severe headaches."

Naturually, there is more to a hangover than just this, such as excessive drinking. It's the buildup of the by-products, such as lactic acid, in the first place that causes it (maybe water would help?)

I assume you were drinking mainly white wine in Italy, and the types of grapes used maybe had less hangover causing agents.
