cold turkey More Idioms  
  1. 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. [Early 1900s]
