Lately, I've been listening to a lot of audiobooks, mainly at bedtime. I've found that using a 30 minute sleep timer is ideal to fall asleep. It doesn't require that the audiobook be boring. The advantage of this is that I'm not wasting the time listening to waves, white noise, a droning voice or whatever. I'm catching up on works of fiction that I don't have time to read otherwise, but wish I did.

The only downside is that out of those 30 minutes, I might remember 30, 10, or nothing. It all depends. So I spend a lot of time seeking backwards trying to figure out if I remember hearing that bit, made more difficult by trying to avoid accidental spoilers.
