Truth: In many ways, this seems related to the "liquor before beer, you're in the clear," myth.
But if you just drink whiskey all night, that's not a recipe for feeling fine the next morning. The type of drink you have can have an impact on how you feel, however.
Since carbonated drinks can cause blood alcohol to spike faster, that might cause a more severe hangover (explaining champagne hangovers).
There's also some truth to the idea that alcohol with more congeners (a chemical component of booze that's more often found in dark drinks like bourbon, red wine, and dark rum) can lead to a worse hangover.
It's not all bad, though. One of the authors of a study showing that also told Scientific American that some of those congeners in whiskey helped "protect the stomach lining from damage."
