Actually, I am almost exactly like you. My problem is that I don't have the mental capacity to simply sit and read a book after a tiring day. However! I will let you in on a little secret. Books do not have to be digested in one specific method only.

Audiobooks! I know you mentioned that you listened to them while reading, but did you try to only listen to them? Personally, I use transportation a lot, I clean, cook, and do some chores. Simply putting in my headphones and playing an audiobook helped me finish more than 8 books in the past 4 months. That is more books than I read for the past 5 years - combined.

Also, try different genres. For me, I am focusing on non-fiction books. Once you realize that you are not meant to remember everything in the book, you will start to actually enjoy the experience. For the fun of it, I sometimes also open my note-taking app and type some interesting points that I listened to, and by the end of the book I have a good summary of the book that I can go back to anytime.

So basically:

1. Try different genres
2. Understand your daily schedule and if you have large periods when you cannot work or be productive, why not put headphones and listen to a book
3. Start with easy books (300-400 pages ~ 6 hours)
