600 mgs ALA recommended for liver conditions

Just joined Cure Zone, not sure what i am doing here (technically speaking - i hope this message gets up).  There seems to be a wealth of knowledge on this site and i wonder if i could pick someones brains.  I have Hep c - for 35 years, but an underlying condition of Alpha 1 Anti Trypsin Deficiency - just diagnosed.  Genetic.  Stops anti trypsin from getting from liver into blood stream where it supports production of white blood cells.  Have always lived very healthily as i have not been able to do anything else - hep c contraction was from an accident when 19.  So i have had interferon - unsucessful. I have also had detected moderate amounts of Blastocystis Hominis - a very difficult parasite to get rid of.  By all accounts i have a very poor chance of anything really, health, long life.  However, i am convinced that heavy metals are a factor.  As i had a kidney infection young, have had many immunisations from migrating.  I have no amalgams and never have had. I'm currently off all grains fruits starch etc - again.  I note that Burt Berkson has used very high doses of ALA for tmt of liver conditions with great success - 600mgs per day with selenium and milk thistle.  So then i read that Andy Cutler says "NO!"  15 mgs ALA at a time every three hours.  No cilantro or chorella.  CONFUSED!  I also can't work out which ALA - so i got the Thorne Brand - sodium R- Lipoic Acid, as this is the most natural.  Can anyone tell me How has Dr Berkson had such brilliant results using something that reportedly releases vast amounts of heavy metals in patients that have extremely compromised livers?!?  Thanks in anticipation.
