Yes i remember you have continued the protocol way beyond after seeing the last one of them. If it is only a few months past, they could not have grown so big, especially the one with multiple suckers, even if you got reinfected right the day after finishing your protocol. These things grow slowly. I suspect you may have them around. You should keep cleansing monthly to keep them in check. I understand you dont want to try praziquantel. If your heath is good, there may be no reason. And it might be a good idea to use some natural enzymes daily to digest eggs to prevent reinfection, such as papain powder, fresh pineapple or fresh papaya fruit.
