documents: #Person1#: What was the party like last night, Jean?
  #Person2#: Not bad at all, thanks. There were one or two interesting people there. Why couldn't you come?
  #Person1#: Well, I couldn't get away from work early. And when. I got home I had a headache, so I had to go straight to bed. But I was over-tired, because I wasn't able to get to sleep for hours.
  #Person2#: What a shame. Why didn't you take a sleeping pill?
  #Person1#: I don't like them. I used to take them when I had to work overtime, you know.
  #Person2#: How many did you use to take?
  #Person1#: Three every night.
  #Person2#: Good heavens. Why did you take so many?
  #Person1#: Because I was under a terrible strain. The doctor saidthey weren't very strong. Anyway, I used to feel awful the next morning.
  #Person2#: I'm sure you did.
  #Person1#: The doctor said I had to be careful.
  #Person2#: He was quite right.
  #Person1#: So I stopped drinking coffee late at night instead.
