Tom had this problem of getting up late in the morning and was always late for work.

His boss was mad at him and threatened to fire him if he didn't do something about it.

So Tom went to his doctor who gave him some pills and told him to take one everynight before he went to bed.

Tom slept very well, in fact, he woke up before the alarm went off. He had a leisurely breakfast and drove cheerfully to work.
"Boss," he said, "the pill actually worked!"

"That's great" said the boss, "but where were you yesterday?"
