Your brain gives you dopamine reward hits when you find a new article or topic, then you form a habit of looking for those dopamine hits. This habit is physically manifest in neural circuitry which your brain uses like a function to simplify its decision making, it uses that process to fill time and release dopamine.

So, you have to retrain your brain not to even start the process, you must be mindful and interrupt the process as it starts. Also, make the barrier to entry into the process very high, make it annoying and inconvenient to do the bad habit.
