I've been doing cleansing for over 6 years now, eating pure vegetarian diet. My last bowel cleanse (Master Cleanser fast) was for 21 days. I've also done a number of 10-12-14 dayers. I've done dosens of LFs. I still do them regularly, but get almost no stones out.
...And I don't dare to claim I'm clean. When I do cleansing, my tongue still gets partially coated and my GI releases junk.
So, keep cleansing, give up meat, cheese, milk, chicken, fish, eggs, sugar, artificial sweeteners, supermarket-bought salt, soft drinks, coffee, black tea, fried foods ....
It takes years...
Good luck.
