I have done a liver cleanse and one liver flush. I have been healing from chronic muscle and nerve pain for several years. I noticed when I did the liver flushes, I got really weak and tired, more than normal. It took days before I stopped the incesant yawning. When I finally flet back to normal like I was before the flush, my pain came back and BAD. So my take on it is our bodies just cant eliminate the massive amount of toxins we stir up all at once. I have done dozens of detoxes and everytime my body freaks out and hurts more. I am just waiting for the light at the end of the tunnel! Oh, one thing that helped me a TON was wet cupping. Heard of it? It is where the doc lances holes in your skin and puts a glass cup over the tiny holes. The suction draws out the stagnet blood. You feel like a new person when he finishes because all the toxins currently in your blood flow out. I have talked to those with fibrom who love it.
