Congrats on day 4 - that's awesome. When I was in very early recovery, four things really helped me: Sleep (as much as I could get, including naps); food (whatever I wanted - I focused on weight loss later); water (tons), and as you've said, books! I went to NY Times bestseller lists from a few years ago and checked out free ebooks from the library, of course the old-fashioned kind work too! Keep it going. You can do this.
