I didn't want to say before, because I didn't want to rain on your parade and come across as negative, but around the time of your 22nd/23rd flush- when you thought you were coming to the end- I could have told you then had a long way to go until the end of your flushing, purely judging by your previous numbers of stones released.
You tend to realise early on, judging by the average amount of stones released in the first few flushes, whether your one of the lucky ones or the in the vast majority who will probably spend three years or more flushing clean.
I've done countless flushes, well over a hundred, but I am still getting them albeit gradually lesser in quantity. I do them very close together but only because I didn't notice any difference in quantity when I did them 2-3 weeks apart. I was still getting the same amount no matter how long I waited.
It is on this issue where I find people like Andreas Moritz slightly frustrating. He keeps saying that everyone should get clean within 12 flushes and seems shocked whenever someone is in double figures. Surely, with all his patients he sees, he could see that the chances of flushing clean in under 12 flushes are slim to none. And the people he consults would be similar sort of folks to the ones on this board.
