    When to Stop or Change the remedy

    While the remedy is acting on your symptoms, you do not repeat the dosage. You must wait to take the next dose until the remedy has stopped acting (that is, when you experience the dip). If your symptoms disappear, you do not need the remedy any longer. If the symptoms change, you may need a different remedy. You must therefore become aware of what is going on in your body. So, be more aware than usual. This is not the usual pill-popping.
