You might try sprinkling a couple of tablespoons of red pepper powder on some food. If you can handle it, take the powder or capsules by themselves. This is what I recommend. The heat from the capsaicin will kill some of these parasites and you should see them dead in your stool. I've graduated from Habanaro's to Bhut Jolokia (Ghost) peppers. This is extreme heat and not recommended for the general population. But nothing kills the little critters like this.
