Hang in there. Each flush, according to my experience with 6 flushes so far, is different and unique, with it's own set of pains and challenges. But my experience is also that each flush gets easier and easier. It took me 3 days to recover from my first flush. Now I am recovereing by the same night. Last flush I went swimming and sunning the next day!
Stay with it and keep us posted. It is worth it - your health, your body is worth it, and you're going to start to feel a whole lot better. Hang in there!
