Parasite cleansing maintenance

I have completed two Liver Flushes recently, and I zapped everyday for a week prior to each flush. I am now beginning my third round of zapping in preparation for a third liver flush. I want after this one to begin flushing on a weekly basis for intensive healht support, but I still have never done the parasite cleansing with the Clarkia tincture . My question:
Am I sufficiently parasite free at this point to begin the parasite maintenance with Clarkia (i.e. 20 drops per day, once or twice a week). This sounds a lot easier to me than zapping every day for a week before each flush. If I maintain weekly flushes, I will be zapping every day!
Please advise.
Thank you very much!!
