Here's my experience in a nutshell:
I've taken Albenza on two separate occasions for my Tapeworm
infection and in no way did it help me. I'm sure it had some effect on the adult worms, but the fact about these drugs is that they don't touch the immature worms or their eggs, so even if you're lucky enough to kill something chances are good that it has lots of frieds who are just going to keep growing, esp. once you're off the drug. Granted, my doc would only give me 3 day rounds of this drug, so maybe you'll have more luck but it doesn't sound like you are...
I have yet to finally free myself from my monsters, but I can tell you that I have much more faith in herbal remedies. They generally keep my worms in check (not sucking the life outta me so I can go about my day without feeling crazy ill)and have soooo many helpful properities for your body that I could write a book on the subject. Meanwhile, these drugs are harsh on your body and TERRIBLE for your liver, which is already overburdened by the toxins your parasites
produce. My advice, ditch the drugs and try HUMAWORM. They have a great reputation for a reason!
