A dialogue at a hospital. A doctor is giving advice to a patient about his diet

D:     You shouldn't eat meat or eggs all day today. And don't eat any rice, except for rice porridge.
P:      Can't I drink milk, either?
D:      No. You may drink it tomorrow, but please don't drink it today.
P:      Is meat all right tomorrow, too?
D:      You'd better not eat meat, but you may eat eggs.
P:       Can't I even eat chicken?
D:      If it's not fatty meat and if it's tender, you may eat a little, I guess. But, when you have an upset
          stomach, you shoudn't eat anything at all for a whole day.
P:       Should I keep my stomach warm?
D:      Yes, if you can. That would be good. I'm giving you some medicine. Please take it after meals.
P:       Yes, thank you. After meals, right?
D:      Yes, that's right. Well, take good care of yourself.
P:       Thank you very much, doctor.
