are you're following the whole protocol (i use andreas's), which includes keeping the organs of elimination open during the liver cleanse process? if so, chances are greater that it is just a healing crisis. keeping the organs of elimination open means doing colonics after every flush (andreas says to do one before and after each flush, but i don't know of anyone that does this). also andreas recommends doing a run of kidney-cleanse tea every 3-4 flushes. so... my first question to you would be, do you do colonics? and, have you done a kidney cleanse yet? if you haven't, i'd work on these things before proceeding. andreas doesn't recommend doing Liver Flushes without paying attention to the bowel & kidneys.
