I didn't do any of those things before my liver cleanses. I flushed out a lot of liver flukes my first 2 cleanses. I did feel pretty rough though for a few days afterwards. After the 3rd flush the recovery time was much faster. It probably would be better though and easier on your body to do the other cleanses first but if that's not possible the liver cleanse still works. I also drank the apple juice for 5 days before to soften my stones which worked very well and was a good thing cause i passed a stone more than an inch in diameter.
