5 days prior to Liver-Flush have been having an apple a day and approx three small glasses of apple juice - but is this enough? Unfortunately haven't been able to get hold of malic acid tablets otherwise would have taken them.
Unyquity's right! You've done plenty enough to break up your stones. My last flush was one of my most successful yet, despite having forgotten to take any malic acid beforehand. Don't sweat it. :)
