I would recommend doing a parasite cleanse before your next Liver-Flush and, yes, keep with the liver flushes. The first several may be a little rough, depending on how congested your liver is. My first flush made me deathly sick! And so I avoided doing LFs for several years. But my liver was still congested once I went back to the flushes. The first several were a little rough and then they got better and I actually felt good afterwards. Once I took them up again, it was the third one where I got emerald green 1/2 inch stones out. After that they were all pretty easy.
Do a parasite cleanse, and then allow sufficient recovery time to be built in to your schedule when you do the flushes, and just hang in there. You will eventually be glad that you did, and your overall health will improve. At least my did.
