I experienced exactly the same thing, but not from the beginning. It got worse after I had a bad flush (#6). A stone got stuck and I felt a big pressure in my liver afterwards. I tried to use the GCG, but it made it feel worse. I havent been able to use it since. It just feels to strong for me. But before it got bad I had one of my better flushes after using the GCG for a month. I have'nt had so many small stones coming out in any other flush.
