"Cold turkey" is a slang expression describing the actions of a person who gives up a habit or addiction all at once, rather than gradually (easing the process through tapering off or using supplemental medication). This is, of course, the cheapest method of quitting any habit, and its supposed advantage is that by not actively using supplemental methods, the person avoids thinking about the habit and therefore, the temptation.

"Cold Turkey" is a song written by John Lennon, recorded by The Plastic Ono Band, and released as a single in October 1969. According to Peter Brown in his book The Love You Make, the song was written in a "creative outburst" following Lennon and Yoko Ono going "cold turkey" from their brief heroin addictions.Brown, Peter.
