Thank you all so much for your helpful and thoughtful advice. I did do a flush last night and that horrible pressure and pain are gone, but I can feel that there is still something wrong. I think I'll take shelleycat's advice and work on supporting my liver a little bit and give it a rest from flushing for a while.
I never thought about putting a strain on my liver by flushing. Thank you for all of your information - it's fascinating! I have been doing the B and P shakes off and on, and will continue to do them. I will also look into the coptis that you mention, even though I have no idea what it is...yet! I will add soups with rice to my diet, that will be a pleasure. Thank you again.
