Some recommend doing a parasite cleanse after the liver is cleansed by flushing. It is thought the any parasites might block the liver if a parasite cleanse is done before. So some think its better not to do a parasite cleanse before, as you did. I did a parasite cleanse during my flushes, I don't think its a big issue either way.
Good work on your first flush, did you get anything as a result of your flush?
