I read your post earlier today on the Liver-Flush Forum, you poor thing.
Others might be more knowledgable than me on gallbladder matters, but I don't think you will find a parasite program to work that fast. You can try to get some stuff together asap, and maybe use castor oil packs to help. For some, they preform miracles. Not sure if you can do this so close to surgery, but what about one additional flush, with the castor oil packs before and after. I read about them long before I was into parasites, and might try that this weekend before my first flush.
If you are scheduled for surgery next week, any parasite program might make you weaker, and some herbal products thin the blood, which is dangerous before any surgery.
