I think the 2 week cleanse should be enough and then do the Liver Flush. I did that and everything worked out fine. Mind you I never did have any indication of parasites but if that is a problem for you, you can always do another 2 week cleanse after the flush. The flush is only less than a day so if you stopped your parasite cleanse for one day it wouldn't really hurt anything. Go for it and see what comes out.
