Detailed Instructions: Given a premise, an initial context, an original ending, and a new ending, the task is to generate the counterfactual context that is aligned with the new ending. 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. The original ending is the last three sentences of the story. Also, you are given a new ending that can provide the new story with the same premise. You should write a counterfactual context to explain the small differences between the original and new endings. More specifically, a story context contains the general plot of the story. And a counterfactual context is a slight modification to the initial context. To sum up, you should write the second sentence of a story based on the premise(first sentence) and the new ending(last three sentences) of the story.
Q: Premise: My nurse gave me morphine to help numb the pain from my surgery. 
 Initial Context: Since the drug was strong, I instantly fell asleep. 
 Original Ending: For the past few hours, I only can recall several dreams. When I woke up, it was the middle of the night. I had to get up in order to use the bathroom. 
 New ending: For the past few hours, I felt excruciating pain. I eventually fell asleep but when I woke up, it was the middle of the night. It hurt so bad when I had to get up in order to use the bathroom. 
A:
Since the drug was mild, I can still feel the pain.
