I tried to email you but that was impossible for some reason. Disregard my previous message. The reason why it was working during the parasite cleanse is because the cysteine is an amino acid and helps deter the ammonia that the parasites are releasing thus preventing the odor. I am doing the similar cleanse and in the upcoming days while the Tapeworm hopefully blows up I have to take some amino acids like cysteine, arginine and ornithine so Ill post how it goes. I think overall its the ammonia from the parasites that are causing these odors in a lot of people. When some try to treat it I think that the parasites recognize it and they pee the ammonia to prevent it from curing.
Sorry about the previous post and i hope that this helps. Thats what I get from not reading the full question!
