I was also diagnosed with this poorly defined condition and found that although liver-flushing has not provided a cure it has made a significant positive effect of my health and many of the symptoms associated with Chronic-Fatigue-Syndrome has reduced and the secondary symptoms which I attribute to prescription drugs have gone. The result has been that I have a very clear understanding of how I feel rather that what drugs make me feel like. I should also add that I didn't choose to flush because of my Chronic-Fatigue-Syndrome but because I had biliary pain associated with biliary sludge.
I don't think it will cure you Chronic-Fatigue-Syndrome but if you want to proceed with liver-flushing be fully prepared. If you are not-confident then try taking the equivalent of 2 apples of juice or whole apples each day for a week and then try a half dose of the olive-oil and citric juice potion.
