Didn't anyone ever test it?

Recently released archives of The Baffler contain a piece regarding the SKYY vodka "no hangover" campaign. Science (plus, what?) be damned, it does quote a nice bit from Kingsley Amis on the spiritual - no puns, please - nature of the hangover. I seem to remember similarly vivid descriptions in Bonfire of the Vanities, but as usual I can't find it.

By the internet's long and winding back roads I ended up at Anthony Haden-Guest's website, where, it must be said, I found that his blog has even fewer entries than mine.
