Thanks so much for your input. I am adding vitamin C for sure. And have tried pyrentel but not with a laxative, that may be the key. I also will check out the citrate magnesium. The mebendazole seems to be helping a lot so I will finish this 3 day cycle and then lay off meds for a couple weeks and use natural remedies and possibly cut out all Sugar including any starch or fruit. Has anyone tried that?
