I have done 3 or 4 this way. I have done a total of 11 flushes so far.
I understand about the oil. I'm taking only 2 oz of oil, and I can barely get it all down. It's past time for me to do another flush, but I have been stalling. I have had pretty good flushes with it. I did get a clear flush once, but got about 30-40 the next flush. So, still not completely clear.
