I've not done her method except for the zapper. You may see odd fragments of things in your stools. If your not also doing a Bowel Cleanse at the same time you may get headaches and feel generally tired as the parasites die off. I highly recommend taking a bit of bran of some type each day to get all that toxic stuff out of you so you can avoid the symptoms. I didn't get tired at all when I did that. But when I did the herbals without the bran it wiped me out. In the end of the three weeks you should have more energy than you did before if you don't have too many toxins built up.
