Just wanted to add, that based on my own experiences, I think HW rocks. I just know that for myself, I need to keep going, and it's what I'll use. I think there can be so many things to do, you just get overwhelmed with products. I don't have time or money to use multiple products or boast about what I found in the bowl. I understand that if you've been sick, and your doctor doesn't listen to you, it's validating to find - prrof - with your own eyes. But I also think that unless you have a microscope and wish to gather your own specimens, you could well be passing parasites that you can't see. So I don't measure success on what I'm seeing in my toilet as much as I measure it by how I feel.
