Success for me is ivermectin albendazole doxy bactrim first 6 months. fenbendazole ivermectin and doxy last 4.5 months but I dropped doxy 2 weeks ago as I work outside in the sun 60 hours a week now and feeling great . I am almost cured and should be by end of summer. lots of worming meds ensures parasites will have their final meal. I am living proof the meds only kill the parasites and not the host if taken consistently over long term for encysted versions of these evil invaders. happy hunting and leave no survivors.
