it scared me too, but all i can say is, when i finally overcame my fear, by the trick of replacing it with anticipation, i only wish i'd done it years before. i have a feeling part of the fear is that a lot of old emotions that have been propping up the personality and belief system, based mostly on "what happened to me" are in danger of being simply washed away, and the personality fears this. That kind of cleansing, a lot of people will tell you, is the last thing we're ready to let go. 'surrender'
(not resignation) is a *big* 'liver' issue.
Maybe look into the Liver Flush that uses malic acid and gold coin grass... very safe, very gentle.
