Yes and it's explained in awesome book The Power of Habit by Charles Duhigg You need a cue/craving -> response -> reward cycle The reward should be slightly unpredictable to make the habit really addicting. So best way to build (or deprogram) a habit: keep a log of how you feel before you do (or don't do) something you want to change. Become aware of your "cue" or craving. Begin to introduce a different response that comes with a reward. For instance, if you don't feel great after leaving the gym you'll never make it an unconscious habit.
