I solved this issue by getting an mp3 player and pirating audiobooks. Cheap and easy. I spent 12 hours deep cleaning my house the other day, while listening to Jurassic Park by Michael Crichton. You should try what that other person said about meditation to address the root cause of the issue, but if you're actually addicted to your phone, putting it away for a long while might be a good idea.
Anyway, I'm reading The Lost World now and it isn't as good as the first book, but it doesn't have Lex in it, which is great. I have no idea why Crichton made her so annoying.
