You know, I could relate to that olive oil. It seemed like the more flushes I did, the harder it became for that mixture to go down!
I was laughing thinking about you plunging that Epsom Salt down your throat and then drinking water. But, then I thought it might be a little too strong and irritate your throat. Any problems? What I would do when I flushed was mix the juice of a lemon with the water (epsom salt) or grapefruit juice.(olive oil) I remember someone saying it helped the taste and it truly does!
I would try another flush when you are ready, though. It may surprise you that you won't have that many stones left!
