hi. i had a gallbladder attack last october and did an ultrasound and found out that i have gallstones. i want to do a Liver Flush first before i do surgery. is it ok to do a Liver Flush after an attack? which one is the best? Dr. Clark's? I dont have a book so im following what is in this website. also do i have to do parasite clensing like taking dewormer or something? thanks.
