Audiobooks for me as well. I read voraciously when I was young, but never seemed to be able to when much older.

Simply listening to an audiobook while driving to work let me "read" a lot more than I thought it would. At the time, my commute was only 10 minutes, but I still managed to read a book per month and listen to my favorite podcasts!

Definitely would not recommend higher speed for fiction, though. For fiction, you're listening to a performance. It'd be akin to watching a movie at 2x.
