Given the task definition and input, reply with output. Given a premise, an initial context, an original ending, and a counterfactual context, the task is to generate a new story ending aligned with the counterfactual context and as close to the original ending as possible. Each instance consists of a five-sentence story. The premise is the first sentence of a story, and the second sentence, which is the initial context, provides more information about the story's context and the story's general plot. The original ending is the last three sentences of the story. Also, a counterfactual context is a slight modification to the initial context. You should write a new story ending that edits the original story ending as little as possible to regain coherence with the counterfactual context. To sum up, you should write the last three sentences of a story based on the premise(first sentence) and the counterfactual context(second sentence) of the story.

Premise: My little cousin always liked Mountain Dew. 
 Initial Context: He would drink it by the gallons. 
 Original Ending: His mom would always buy him more. He has diabetes now. But he won't stop drinking Mountain Dew. 
 Counterfactual Context: He would only drink it on rare occasions.

His mom would buy it sometimes. She knew that he would get diabetes by now if he drank it everyday. As he got older he stopped drinking Mountain Dew.
