I guess I'm cool coming out and saying it. Out of curiosity I bought some helminths online and infected myself. I was inspired to do it after reading a book called An Epidemic of Absence.

I can't say a whole lot -- positive or negative -- came from it, but it was easy to do and inexpensive. So even though the article says you shouldn't try it at home, I did. I consider it safe. I'm not a doctor, I just read a lot of PubMed, so take that for what it's worth.
