That is my question as well. What I read is exactly like peggyaus said - you need to wait a little bit so the stones will move to the front. In my case - the flukes too which I believe is more serious than the stones. That explains many issues I have been facing my entire life, heopfuly now finally I will reach that state of health I have always dreamed about.
The second part is the colon cleanse which Andreas Moritz said is a must before the flush and it normally takes at least 3 days to do it. So - I guess you can do it non stop but I rather give my body at least one week of normal eating and time to recover. During this time I will do a parasite cleanse that would hopefuly weaken the flukes.
If you take a look at the pic I took, you would see that the liver flukes seem fresh and juicy and not just dry skin, which in my opinion shows that they are still alive. Almost look like snails.
