I'm just starting my third week of this program. I've never done a cleanse before so I researched a lot of options and kept coming back to their website. I have to admit, the money back guarantee was very appealing. So far, I'm very pleased with the results. I've had problems with constipation for years and I want to cry every morning when I go to the bathroom like clockwork. Some days I go a few times and others it's just in the morning but I feel cleaned out when I go. I no longer have that constant feeling like I have to go, but can't. Another huge change is that the constant join pain I've had is completely gone. I also suffer from yeast problems so I'm hoping this will be an important step toward resolving that, too. I eat very clean so I haven't modified my diet at all. Hope this info helps.
