http://en.wikipedia.org/wiki/Cold_turkey has some possible answers :-)

Cold turkey refers to the clammy, cold, sweaty and goose bumped state of the heroin addict that is trying to "kick" the habit. This happens when the junkie decides to give up heroin without any sort of support mechanism - such as methadone - to take the place of the heroin. The body reacts by turning cold, clammy, sweaty, and the skin resembles that of a cold turkey. 'Without preparation'. First used in correlation with withdrawl from an addictive substance in the 1920s with regards to heroin addiction. The idea being that "cold turkey" is a food that requires little to no preparation to eat - hence doing something "cold turkey" means the action will be done without preparation & immediately. Also connected to the notion that the symptoms of withdrawl from many substances include cold sweats (moisture), and sallow skin - much like that of a cold, dead, turkey. http://www.urbandictionary.com/define.php?term=going+cold+turkey Immediate, complete withdrawal from something, especially an addictive substance; also, without planning or preparation. For example, My bad shoulder forced me to quit playing tennis cold turkey, or I'd never done any rock climbing, but decided to try it cold turkey. This term may have come from the earlier expression talk turkey (for blunt speaking). At first used strictly for abrupt withdrawal from drugs or alcohol, it soon was transferred to quitting any habit or activity. By 1922, cold turkey was not always a leftover from Thanksgiving dinner. For an addict, it was quite the opposite. "This method of sudden withdrawall," explained a writer that year, "is described in the jargon of the jail as 'the cold turkey' treatment," It meant "to immediately and completely give up a substance, such as narcotics or alcohol, to which one was addicted." The shock to the system was such that few addicts voluntarily chose it. "Mention of the 'cold turkey treatment' gives a chill of horror to a drug addict," said Newsweek in 1933. "It means being thrown in jail with his drug supply completely cut off." And Mickey Spillane wrote in I, the Jury (1947), "I doubt if you can comprehend what it means to one addicted to narcotics to go 'cold turkey' as they call it." This use of cold turkey is an outgrowth of a previous sense, attested as early as 1910, meaning "extreme plainness and directness," going back to talk turkey, attested in 1830. Carl Sandburg used the term this way in a 1922 letter: "I'm going to talk cold turkey with the booksellers about the hot gravy in the stories." http://www.answers.com/topic/cold-turkey Origin: Of course, the term 'cold turkey' in the literal 'cold meat' sense appears many times in recipes - 'cold turkey salad' etc. Neither of the meanings above appear to have any allusory link back to that though. The most common use of the term is now in relation to drug withdrawal. The earliest reference I can find to that is from the Canadian newspaper The Daily Colonist, October 1921: "Perhaps the most pitiful figures who have appeared before Dr. Carleton Simon..are those who voluntarily surrender themselves. When they go before him, they [drug addicts] are given what is called the 'cold turkey' treatment." The 1936 edition of American Speech gave a definition of the term: "Cold turkey, treatment of addicts in institutions where they are taken off drugs suddenly without the 'tapering off' which the addict always desires." The 'plain talking/getting down to business' meaning of the term is largely limited to the U.S.A. The English newspaper The Daily Express explained that for an English audience in a January 1928 edition: "She talked cold turkey about sex. 'Cold turkey' means plain truth in America." There are many uses of the term in U.S. citations from the early 20th century. For example, this from The Oakland Tribune, August 1915: "This letter talks cold turkey. It gets down to brass." In the state of drug withdrawal the addict's blood is directed to the internal organs, leaving the skin white and with goose bumps. It has been suggested that this is what is alluded to by 'cold turkey'. That seems doubtful. It is much more likely that the allusion is to the direct, no nonsense approach indicated by the earlier 'plain speaking' meaning of the term. http://www.phrases.org.uk/meanings/96950.html
