Girlfriend or some work/job that is getting all of your powers for the day and when you came home tired as S#@& you just lay down and sleep until the next morning !
One must remain busy so that they have focus on better things then all this always. Another thing takes up some physical activity, like jogging, cycling, working out for hours if totally free and nothing to do etc. Meet friends and cheat with them, go for overnight trips with others or spend time at friend’s place etc so that you will not do such things in front of them.
