Para Farm, opinions and questions

I have been suffering from pinworm for about 40 years. Last year I underwent 11 pyrantelum treatments and 3 this year. I haven't eaten sweets at all for 9 months. Once I ate a piece of cake 1.5 years ago and on the second day there was 1 parasite, then another treatment, zero sweetness and after 3 months I ate 1 piece of little sweet dough again. On the second day itching and again appeared 1 pinworm. Subsequent treatments every 3 weeks, zero sweets and daily cabbage juice in the morning and evening, washing at 90 degrees, treatments of the whole family and success. A week ago I ate 2 scoops of ice cream, not very sweet and on the second day there was again 1 pinworm.Alive, moving. For the next treatments I do not have the strength, my stomach gets off. What should I do? :( for the rest of your life even a scoop of ice cream do not touch? I have any eggs attached to the intestines or what and wake up under the influence of sugar? Where to look for help and what I no longer believe in it.
