Go for a week without making one trade. Observe and learn which trades you should take.
Week two, take one trade in the morning and one trade in the afternoon. Observe and learn which trades you should take.
Week three, take two in the morning and two in the afternoon. Observe and learn which trades you should take.
If that doesn't have some affect, quit trading . . . if you have to "force" yourself to trade less, you have no idea what you are doing apparently.
Of course, you could trade with real money . . . which will rid you of your habit the hard way --> money runs out.
