I too second the cs and the Terminator. The fact that you improve after flushing, if only for a few days, means that as you keep on flushing you will eventually get it all out. Your symptoms return because the backed up stones and stuff keep moving into the space the you have cleared with your flush.
Flush every 2 weeks if you can. Many people need more than twenty flushes, and many people don't need that many. It depends on your age too.
I have done 47 flushes and I am not finished yet, I can feel the lumps in my upper back and I look forward to my next flush. At 67 I have sinned against my liver a lot more than younger people.
You are on the right track, keep working on it.
