I would go to Ask Humaworm forum and read the threads. Very informative forum.
I was speaking to a friend of mine who took a cleanse from another product and had minimal results. Then I was researching worm cleansers and I ordered Humaworm who every one raves about. I am pleased to say that I have been on it since Jan 22nd. I do drink a lot of water and stay hydrated.
Good luck to you.
