I do this flush all the time. Before you open it may be you should send it back. It is a different flush than Clark's.
Or you can use the products and not follow their flush.
There are different protocols on the forums.
The Barefoot Herbalist and Andreas Moritz
both suggests to clean the bowels before to do the parasites. The dead parasites
can clog you up so it is better to have your colon clean. Andreas even suggests for the same reason to do the liverflush next.
You can read under cleansing all the different ways of doing things.
Just follow the Clark times and after the oil rest for 20 minutes and then stay up again till you want to go to bed. Just set your alarmclock for the 6 am epsom salt.
I would use the prepping for the flush from the Oxypowder
