The idiom comes from the image of a turkey suddenly going limp after being shot, symbolizing the immediate and drastic nature of the change.
Here's an example:
* "After years of smoking, she decided to quit cold turkey. It was tough, but she managed to do it."
This idiom is often used to describe quitting harmful habits like:
* Smoking
* Drinking
* Drug use
* Gambling
* Other addictions
However, it can also be used in a more general sense to describe any sudden and complete cessation of an activity, even if it's not considered an addiction.
* "He quit his job cold turkey and moved to a different country."
It's important to note that while quitting cold turkey can be effective for some people, it can also be very difficult and even dangerous for others.
It's always best to consult with a doctor or other qualified professional before making any significant changes to your health or behavior.
