disapointing 3rd flush

Hi,

My girlfriend and I did our third liver flush yesterday and did not get any stones out this time. In the previous two, we counted about 30-50 stones each. To prepare for this tiem we decided to try the malic acid instead of the apple juice. We drank 2000mg of it each every day for five days up until the cleanse. Could this be the cause of not flushing any stones out?

I could believe that one of us does not produce any stones in a flush but since it happened to both of us, it makes me think something else went wrong. Is there such a thing as bad malic acid?

The bottle that I have here containing the powder, I bought at a natural clinic pharmacy and it says it was packaged in June 2003. The bottle was sealed air tight when I bought it so I don't think it could've gone bad. Malic acid doesn't go bad does? It tasted like I thought it would, the sour bitter taste like citrus and similar to what you can taste in red wine as well.

What do you all think? Should I just give up the malic acid and go back to apple juice or is there something else that might've caused for this disapoiting third flush?

thanks,

fred
