A mother is talking with a doctor about her son's sleeping problem.

Agatha: Doctor, my son seems to be having trouble sleeping. He stays up until 3 or 4 in the morning.

Doctor: Is he (tied) (down) with a lot of work ?

Agatha: Not really. He has the same amount of work as other students. But the problem with him is he (dozes) (off) in school.

Doctor: The teachers must not be happy. Why don't you suggest listening to some music before bedtime? Besides that, (cut) (down) on television and video games at night.

Agatha: I'll try that. Thanks, doctor.
