You can pretty much do Liver Flushing when you want though NOT when you are ill. It is best to do it over a weekend so you can relax. Follow the directions for flushing such as Hulda Clark , or Andreas Moritz . You have done well doing a colonic to clean the colon!
You need to time it so you do one after the flush aswell (about 1-3 days after), because it is VERY important to clean the colon after flushing. Read up on what Liver Flush recipe you want to follow, and go for it.
