The concept of a "not-to-do list" seems useful here; instead of things that you want to do to check off, they're habits or actions that you do not want to do. "Do not watch the next episode of a TV series without getting up and moving around" could prevent you from launching an unintentional marathon, by giving you an opportunity to change what you're doing with every episode.
