So I also am afflicted with this. They love to reside in your bladder as well. I also have had many issues getting rid of these demonic parasites. I can tell you I have found a better med that will help you. It's oxibenazole. It seems to be fairly gentle no bad taste and kills them almost instantly. I urinated out a clump of them about 40 min after taking the meds. I am not sure on dosing so I personally am playing it safe but I found hope in this med. It is the only one that has worked. I feel movement in my head and lymph system. I hope this helps
