I think sleep (and getting in and out of it) is hugely individual and you need to work with your own physiology. My discovery was that I can't "think" when other people are talking because I think verbally. So putting on speech and lying down == sleep. I've listened to podcasts or audiobooks every night for several years now and am asleep within 5-15 minutes. The other benefit is I've also listened to hundreds of books and podcast episodes, but all in tiny chunks. The next night I seek to the spot I last remember and continue.
