have you considered Andreas' pre-flush protocol?

Have you considered trying Malic Acid for the week prior, as Andreas recommends? He recommends either Malic or Gold Coin Grass, as they both soften stones... also he recommends herbs to de-congest the liver and get it ready to flush. Here's his links... (places are in the USA though).
