Thats sounds like a good explanation why we need acidic citrus juice along with the Oil. Last time I used Coconut Oil instead of Olive Oil. Coconut Oil was liquid at room temperature, so I drank the CO and immediately drank 1/2 cup of freshly pressed Grapefruit Juice. Thankfully it worked!
So U could do the same with OO. Drink the OO (Olive-Oil) and then follow it with some GJ. I guess that will work as well.
Next time I am planning to flush again with Coconut Oil. I like it better than OO.
