Don't know if you saw my last post to you on the Bowel Cleanse Forum , but after you described what it looked like it does sound like it could be a worm. I have seen tape worms that fit this description...sort of transparent white with a darker center that I believe is their guts. Does it look like it is segmented? And do you see a head on it? One of the problems with tape worms is that if you don't get the head out the worm will just start growing again! A thorough Colon Cleanse and parasite cleanse including CoQ10 would probably be a good idea just to make sure.
