this whole parasite thing is creepy and confusing. Unless you actually SEE them, or have really marked symptoms, how can you KNOW if they're there?
Take comfort in the fact that you feel you have a good doctor who is treating you. Make sure to help him/her out by making whatever dietary changes you need to make to help keep the parasites gone.
And yes, it is nice to know you're not alone, and that this forum is available to us to commiserate with and support each other on.
