I'm on my sixth day of Clarkia and haven't seen anything. I haven't felt anything either. Then again, I didn't really want to see any worms. Maybe not everyone has them. For years I've taken tons of vitamin C, average around 8000 mg daily and I don't eat meat, so maybe I don't have a whole lot of parasites to begin with. Who knows!? I'm going to do all four suggested for the Clarkia .
