Congratulations on expelling some worms during your colonic! Please do not allow the "gross factor" to deter you for long. It is of course much better for your health to knowingly have the parasites outside of you than unknowingly inside of you. As for diet, from what I understand, it is very important to eat a diet that parasites do not thrive on. The presence of parasites is probably what makes such a notion daunting for you. The diet is not always easy for me to keep either, but I feel much worse overall when I do not.
