I agree with Bythc. I'm the poster who first wrote my experience with experamenting if anyone here tried a horse wormer. I took it out of desperation and it sounds like you are having the same exact experiance as I. The next day, I passed tons of seeds. As the week went on I kepted passing visable parasites. With animals, you only do it every six weeks. Let your liver rest in between before taking anymore too soon. Belive me, the parasites will keep comming out during the week.
