I did enemas while fasting. Once you do one, you will always want to do them for cleansing. THey make you feel soooooo good and clean!! The salt water flush made me gag and very sick. You also risk dangers in the SWF. I have read posts where people did not use enough salt and ended up in the hospital, or others had blockages in their intestines so the water got stuck... Enemas are safer in my opinion and experience.
