Hello, Likefasting! I personally have never tried ColonBlow, but my cousin did with great results. I used Dr. Natura's herbal Colon Cleanse (it lasts a month) instead. It worked great and I even saw some rope at one point. But I have never had problems with constipation, so I don't know if this will help you or not. I doubt that cleansing the colon can ever be a bad thing, though. God bless and thanks for your kind words.
