Janopause
n. The practice of abstaining from alcohol for the month of January.

Example Citation :

The Janopause describes the post-Christmas abstinence from anything remotely pleasurable.

Look around your workplace and you’ll see people on the Janopause everywhere. They’ll be the ones with a litre bottle of Brecon Carreg on their desks, a packet of pumpkin seeds and an expression of utter misery.

—Carolyn Hitt, “Abstinence and grim resolutions of Janopause just don’t fit in,” Wales Online, January 9, 2012
