:scratch: So tired of reading opinions. Most of you worm once & then again in another 10 days correct? Im one of those ppl who has never had a fecal done. Just read somewhere else not to ARRG cause supposedly causes resistance. It's my understanding that resistance is due to UNDERdosing; ie either not large enough dose or no second dose to break the cycle. Or the simple fact that alot of them dont work anymore to begin with. Thanks!
