If you want another story about a guy in Europe and his tapeworm, I heartily recommend the novel "Filth" by Irvine Welsh.
Huh. I think I *wanted* to like his writing more than I ended up actually liking it. I think I tried Trainspotting and Ecstasy. Heh, quote from http://books.guardian.co.uk/authors/author/0,5917,-168,00.html - Welsh now readily admits that "Ecstasy was like somebody writing an Irvine Welsh exploitation book."
