M: Well, I had to work overtime yesterday. And when I returned home, I had a headache, so I had to go to bed straightly. But I was exhausted, so I just couldn't get to sleep for hours.

W: How many did you use to take? M: Three every night. W: Good heavens. Why did you take so many? M: Because I had great pressure. The doctor said they weren't very strong. Anyway, I used to feel awful the next morning. W: I am sure you did. M: The doctor said I had to be careful W: I couldn't agree more. M: So I stopped drinking coffee late at night instead. (20)
