It did seem to put in a whole lot more energy into my system. You just have to remember to have a pint of very warm water upon arising to stimulate your bowels. She explained that some of the herbs help move things into your colon. Constipation happens when there's too much in there and you're not having complete BMs, so it all has a chance to dry out (and get stuck this way). As long as you drink the hot water, and move around, the herbs *help* bms.
I just did this flush using about a third of each bottle (rather than going on for three weeks as recommended, since I didn't have the time).
