Later on, it was sometimes hard to tell whether he was larking round or serious: as a narcoleptic, he would often lull journalists into a snooze and then snap to, razor-sharp, with the answer to their questions.

来，有时很难区分他是随便玩玩还是认真：他经常像一个嗜眠者那样把记者也搞得昏昏欲睡，然又突然清醒犀利地回答他题。

Now, is he an actual narcoleptic or does he have severe sleep apnea?

现在，他是真有嗜睡症，还是严重睡眠呼吸暂停综合征？

So he picked me up, and he was a narcoleptic.

于是他来接我，而他有嗜睡症。
