seeing doctor对话

Hello doctor.
Well,what seems to be the trouble,Mr.Willams?
It's nothing serious actually,doctor.It's...well,I get tired very easily recently.And I often doze off during meetings,
office hours and sometimes even while I'm dining.
How long has this been going on?
About 2 months.I didn't pay much attention to it in the beginning.But you see I got fired this morning.
I dozed off while we were having an important meeting,right in front of the boss.I was very embarrassed.
Well how is your appetite?
Pretty good,I'd say.
You haven't lost any weight,have you?
No,doctor.I've actually put on two pounds.
Unbutton your shirt,please.
Well,docotor?
You'll have to have some laboratory examinations to know for sure.
What examinations?
A blood test and a urine test.You can come back next week.Say 4PM to see the results.
