Thanks so much for your thorough and helpful reply. Goodness, a month sounds like a nightmare. Mine tend to last for two weeks, and it's still a frightening experience.
It's good to know that the blockage is likely a result of parasite death. In the case that I can't get unblocked very quickly: do you think it's safe for me to continue taking the tincture while I'm obstructed? Will that just make the toxins re-enter my body over and over because I can't evacuate them, and make the obstruction worse?
