So, Parazapper, do you do the Herbs Dr Clark recommends? That shoulda whacked any tape worm. The herbs are for exactly that reason, because the current can't get that deep inside usually.
But I think it's how you define 'cure'. I say, yes, I'm cured because I no longer have any of the symptoms and keep deparasiting regularly (especially now, eh?)
But it's like taking a shower. Of course you'll get dirty again after a couple days, although the shower killed your 'symptoms' of dirtiness. parasite reinfestation is almost that fast as well. If you don't shower once a week at least, your 'symptoms' of dirtiness will be back again, full force.
I think to stay symptom free, aka cured, you have to be proactive about 'taking a shower' regularly. :)
