dear Natura
C-potencies, as well as Q-potencies, should not be repeated without a change in potency. Repeating exactly the same potency can lead to uneccessary problems, as a proving can be induced.
It would not be good homeopathic practise to repeat or uptake a remedy without previous reassesment of the case.
In your own interest, and to avoid difficult situations, I would advice you to study homeopathy a bit more in depth in Hahnemann's Organon and chronic disease.
