The Liver-Flush process not only it takes alot from your body, specially the process your liver has to go through but it also require special diet and ES that will reduce the balance of minerals, vitamin and physical vitality.
In addition you probably read that the minimum 14n days between flushes been thought to let the stone raises from the depth of the liver to the surface to easier being flushed.
I also suggest that you'll not become addicted to the flushes. Do a seri of 7-8 flushes and let your body rest for 6 month or longer than do few more and let your body rest again.
If however you have attacks doanother one - first of all try the ES it may solve the attacks pain
