Forgot to mention, few weeks ago I found a post in which someone said they had added 3 drops of oregano oil to the OO/coke potion and they had passed more stones than ever before. So I thought why not try it and ordered some from barefoot. Although I'm giving the coke all the credit, it may be the oregano oil had something to do with it. I tried to find the post to them thank but have been reading so many posts on different forums I couldn't find it. So why don't you give this a try and hopefully it helps. Let me know.
P.S. I used 5 drops! This is potent stuff.
Also Pioneer said to use a 1/2 tablespoon of baking soda to kill bugs (have you done a parasite cleanse). I used the baking soda and passed a few liver flukes. parasites could hinder your passing stones
