I don't know if this will help, but my advice would be not to eat apples, just juice them or puree them, take lots of Epsom Salts , use castor oil packs and try to rest.
Are you doing the flushes so close together just to alleviate pain?? You liver might need a rest.. The Epsom Salts should reduce pain without the necessity of a flush. If you can wait a while it might help.
