And don't be afraid to take more than the recommended dosages, with caution, of course.
Learn how to listen to your body. It will let you know what it needs, once you understand the difference between a craving that is caused by the parasites and the satisfaction of nutritional fulfillment.
You will always be vulnerable to reinfection. Staying free of parasites is a life long endeavor/commitment. We worm our cats, we worm our dogs, we worm the livestock. Why are we NOT worming ourselves?
Once you get your parasite load reduced significantly, plan on doing routine maintenance for the rest of your life, and you will stay healthy.
