A：Are you feeling better today, Bill?

B：Well, it's hard to say. I cough a lot in the evening.

A：You'd better give up smoking. It's bad for your health.

B：You're right, but you know, it's hard to give up an old habit.

A：But you should make up your mind first.

B：You know, I often have to work til late at night. I need something to keep me awake.

A：Why don't you go to bed and get up early? You'll have the same time for work.

B：Thank you for your advice! I'll try it.
