liver flush/epsom salts.. Need some help with this.. Thanks:)

hey there! this ? is for anyone who would like to help.:)
I have been doing Liver Cleanses for the past month or so, but have not noticed any stones come out.. The thing is, is that I have been using about 1 tbsp. of Epsom Salts instead of 4 tbs.. like they say.. I did this becuase I was having a hard time taking all of that much, and I read on here.. that Agnes recommended taking a 1/4 of the Epsom Salts dose for people that are sensitive and pregnant mothers. etc.
Anyways... I just read somewhere not to use less than 4tbs.
IS THIS NECESSARY? DO you have to take this much to get rid of the stones? What about 2 TBS? OR what about using another product such as BIOXY?(which is magnesium peroxide..) instead of magnesium sulfates... let me know.. I really appreciate some help.
Thanks.
