I'm sorry to hear that you have been having parasite issues. I had a friend who had something very similar recently and it took her a long time to find out what was making her so sick and then to get rid of it.

That being said, I remember that in discussions with her and a group of friends that probiotics were mentioned and that she should be wary of taking them while the parasite was still there as they feed off the probiotics. Probiotics were mentioned to be helpful after parasites were gone....

Now this is second/third hand information. But I thought I should mention it. Perhaps a little more professional advise about probiotics and parasites before you start taking them. My friend saw a naturopath but your homeopath might be able to help you out.
