Be careful how you talk about any habit you are trying to break. Don't go out with friends and talk about how you are trying to break such-and-such bad habit and it is so hard. The more you say it is hard, the harder it will be. Actually, you would be better off not to talk about it much at all. Keep your goal between you and God, and possibly one or two other trusted friends or family members whom you want to pray for you and encourage you. When you are weary of doing battle with your wrong desires, think of how wonderful it will be when the bad habit is a thing of the past and a new habit has taken its place. Focusing on developing the good habit you want to establish will automatically help you enjoy freedom from the bad habit.
