I think what kept me off was mainly reading tech documentation or programming (e)books throughout the day. I don't really want to see more books when I'm trying to chill out.

But the easy and palatable suggestion is a good one. There's no shame reading books written for kids or young adults no matter how old you are. Heck, I bought a book for little kids with lots of beautiful drawn pictures for me some years ago. The wombat and his quest for carrots is a lovely story and I'm not ashamed to admit.
