Sounds great! Started with the complete Hulda Clark parasite cleanse, which seems to be more or less the same as humanworm on a weekend. Read about strong die off in the first days and this was exactly what happened to me. The first 2 days were really bad, I couldn't sleep much and had severe stomach pain. On the third day pain got better and I hadn't had anymore such strong problems.
I had not much visible dead parasites, just some rice size looking pieces over more then a week, though I suspect most parasites are just far to small to be visible.
I'd go on with it, drink lots of water, it seems critical to go on in order to kill parasites in all stages. If you stop to early, you might be contaminated pretty soon again. I am on day 20 now and only the first 2 days were really a challenge!
