4th liver flush tonite-will try mag. citrate

I will be doing my 4th Liver Flush tonite (Dr. Clark's protocol in the past). I just don't think I can tolerate the Epsom Salt so I am going to try mag. citrate. I bought a product at health food store called Natural Calm.
Tomorrow is a full moon. Is that when you get better results or on a new moon - which I noticed is the 20th of this month.
I passed about 100 pea sized green stones on first cleanse, 40 two weeks later and 100 three weeks after that. I wonder if waiting 3 weeks instead of two was the difference between passing 40 and 100.
It has been two weeks since my last cleanse.
