Yeah I feel that; I've read so much on this forum and I pick and choose from people that have had successes, but I'm still not cured and it's extremely frustrating. Good advice on the enzyme wash. I think my boyfriend picked up one of the parasites I have unfortunately, so I totally get you quarantining :/
As for Prazi, I'm not sure if I have strongyloides or schistosomiasis or what, and there's some evidence prazi works for schistosomes (there's a lot of stuff on this forum, or if you google for studies). I actually did feel like it was helpful to do a double dose — 1200mg 3x day — during the new moon; generally I do 600mg 2-3x day.
