I did 3 flushes in 3 days without the Epsom Salts . I didnt know how long to wait but wanted to be free of the pain so did only the olive oil and lemon juice and passed my stones with no problem. by the 3rd flush I was not seeing any stones so assume that all is well. THE PAIN IS GONE!!! It has been over a month now with no problem, so I plan do do a monthly dose of olive oil and lemon juice regularly to make sure it doesnt happen again.
