If the worms can live 20-30 yrs then sadly that means I will die before them. The gigantic ones just wont die. They are stunned but revive and so I have to keep on meds forever. This is a hardship. I am dealing with about 8 large tapes, ascarias and flukes. So tired of the whole ordeal everyday meds and herbs month after month and feeling sickly from herx and toxins. I cant have a normal life. And I dont want to be sick anymore. Prazi causes migraines and i also have vertigo daily from a possible spinal fluid leak or blockage. I have made tons of progress over the years, killed hundreds of small worms, but the large ones are keeping me in fear and sick.
