I've been reading a lot in this forum and I am just wondering about a few things - I am planning on doing The Master Cleanse next week - I would love to end it with a liver cleanse but I read a little bit about it and they strongly recommend that you do a parasite cleanse first - that is recommended for three weeks before the liver cleanse in order to remove all the stones - the parasite cleanse is pretty involved - is it really necessary to do the master cleanse, then the parasite cleansing for three weeks and then do the liver cleanse. Also, is there any pain involved (intestinal cramping, etc) during The Master Cleanse or the liver cleanse - especially with passing the stones during the liver cleanse - is that painful?
