If you don't take a break from the cleansing, you may develop resistant parasites, and have a much harder time of getting rid of them. You can take in-between-spices that help kill them off, but don't make them super resistant.

Per Humaworm: Take 1/4 tsp. each of garlic, onion, thyme, sage, cinnamon and cloves. I add the first 4 to stir-frys, or soups and the cinnamon and cloves to oat bran, or oat meal. You can add them to what ever food you like. I've read that freshly ground cloves may be the only thing that kill's eggs.

I like to eat a lot of fresh garlic and onion everyday... both kill parasites.

I also use aloe vera juice often. If you use aloe vera juice, as it kills parasites, you must take breaks from it too. I use it for a week, and take a break from it for a week or two.

Another thing that helps is to add fresh lemon juice to water as it helps kill parasite eggs.

Oregano oil drops, olive leaf, pau d'arco can all be used. Check with Humaworm.

I like to eat a lot of pineapple for a couple of days... I've read this kills parasites.

I'm sure I'm not thinking of everything right now!

I would not quit if I was getting results. Why change products if you have one that is working for you? However, it easy to confuse undigested food particles with parasites. Make sure that the critters you see in the toilet are really critters. Think about what you are eating. When you start cleansing the bowels, stuff comes out more quickly and it is often not very well digested. It is easy to mistake salad, mushroom, corn, peanuts, any kind of nuts, sesame seeds, tomato peels and the like for parasites. If the stuff coming out is accompanied by mucous, gray oily substance, black tarry substance and terrible odor, you are getting at the parasites. If it doesn't stink really bad, it may just be fresh food that didn't get completely digested.
