input question: W: Well, I've been having bad stomach pains lately, doctor. M: Oh, I'm sorry to hear that. How long have you been having them? W: Just in the last few weeks. I get a very sharp pain about an hour after having meals. M: I see. Do you get this after every meal? W: Let me think. No, it's usually in the afternoon, after lunch. M: Well, what do you have for lunch? W: Oh, I mostly just have a quick hamburger and rush back to the office. We're very busy at the moment. M: Well, I don't think it's a serious thing. Maybe you eat too quickly. It's bad for your health. W: My husband is always telling me that. M: Anyway, I'll give you something for it and see what happens. Take the medicine three times a day. W: After meals or before? M: After eating. W: Thank you, doctor. M: You're welcome. What was said before this conversation????
