Thank you for a very interesting and very detailed post; one where even some humour has its place. :-)
I wish I could answer your questions, but as I haven't fought the same symptoms as you did, anything I say is just a guess.
Going through the details of your history and suffering, I sure would recommend doing some more rounds of Humaworm in the future, with the appropriate breaks in between (three month, more exactly).
In the case of your persistent focullitis and related nuisances, I sure would do an anti-bacterial, anti-virus cleanse as well, to fight that from the possible angle of bacterial or virus infection. This is a wild guess, but I can't place your symptoms along anything I know about parasites and stuff, therefore this poor advice. :-) By doing these cleanses, you can't loose a thing, you can only gain; but to what extent, I don't know.
I hope somebody will come up with a more educated opinion than mine is here. And recommend what is needed based on experience and not on simple guessing as I did here.
