Hi J - I realize this is very old and you are likely much better and not on Curezone (I hope :)). Just in case you are around, I want to know if you saw more of these. Also, how are you doing now? Did you eradicate the issue? I have had several of the same things in my toilet bowl and am seriously puzzled. I think they are worms but one can never be sure. There are so few concrete resources available to us parasite killers! Thanks, Ww
