I'm also having the same problem with the humaworm and humacleanse even though I've been drinking lots of water and eating lots of fruit and veg. The only thing that seems to move my bowels is a teaspoon of castor oil followed by a glass of warm water thirty minutes later. But I'm not sure if I should be doing this daily especially since I've read that the castor oil can also be used as a liver flush. Someone also said that I could be sweeping away the herbs with the castor oil.
