As I mentioned in a post above, I totally had the same confusion. I decided to research and spent months. You may not have the same issues as me, but I posted my plan that I came up with, and described the order and why I chose certain products. You can see it with the link below.
By the way, before I did the Liver Flushes I had an ultrasound to see if I had anything huge that could cause problems. Also, I feel that there is some slight risk involved, as you will see if you read the archives. I finally decided to do it, and it really helped me. I did not do the parasites first as I was having really intense gall bladder discomfort. It went fine, but I would have done the parasite stuff first if I could have.
