I am all for drinking the apple juice, think doing it for 1 week prior is enough though. I wil say this, I will not fast for anybody! I love my food and when I go hungry I faint all over the place. The only time I go without is on the day of the flush from 2p.m . I still continue will liquids though as I don't think its good to dehydrate. The last time I flushed, I sipped on Coke all afternoon.
blah I hate that stuff, We dont even have cordial in our house as I'm an organic gardening health freak, but if it helps break up the stones, I'll do it.
