I don't have any actual experience with those products but I reeeeallly think they're a bad idea in general. I think going about it the natural way (as you're doing) is really the best thing. I don't buy into the ideas those companies are selling you (that there's crud/toxins trapped in your body and you need to "cleanse" them out). If you're pooping regularly (as you are) you're fine! I'd rather keep that pound or two on than spend hours in agony expelling all kinds of stuff and dehydrating myself. I took a simple laxative once and thought I was going to die from the pain. These things like "colon cleanse" etc can only be worse.
