Congratulations on a great flush.
I will keep to my shot glasses of OO (Olive-Oil) until I have trouble with them, then I may try it your way.
My last 2 flushes have had the largest stones and my best results to date. I am up to 8 flushes.
My first few flushes only released the grainy sandy stuff, but now that I have cleaned some of that out, it has made way for my stones to start moving through.
My gallbladder is aching and letting me know it is time again for another cleanse, so my 9th flush this weekend, and I am feeling positive of a good result.
Good luck with your Coke flushes in the future.
