Rinsing the sponge

I don't remember which of my friends I first heard use the expression, "Rinsing the Sponge", but I think it may have been T Rice. I decided yesterday to see if anyone else uses that expression, and found a number of hits on housecleaning, and a couple others that I won't mention, but nothing about my intended meaning: a brief hiatus in consumption of alcoholic beverages to allow the liver to recover. Usually this act occurs after a particularly painful overindulgence, and includes almost excessive consumption of good old H20.
