is this normal?

My first flush was mildly successful (about 65 pea-green stones), my second one produced nothing (very disappointing, and yes I followed Dr. Clark's recipe to the letter!) and my third was again successful...yet this time it's 3 days since and I still haven't had a formed stool.
Is this normal?

Did I take too much Epson Salts? I took the same amount as the 2nd time (4 T spread over that night and next morning).

I'm slowly learning the best ways for my body to take the flush... I dissolve the ES in an ounce of hot water then add grapefruit juice, shake hard and put in fridge to get cold. It doesn't taste quite that bad anymore. Maybe that's why I drank too much?

I also had a bad run-in with a bottle of rancid oil. It was Davinci (or something like that) xtra virgin cold pressed. But I couldn't get it down. Had to run out for another bottle (different brand this time!).

I'm ever hopeful I will flush all these stones out. My doctor is patiently waiting for me to fall on my face and schedule surgery, but my husband says I'm plainly stubborn and determined to make this work (I ADMIT it!)

Thanks for listening. For anyone reading this that HASN'T tried the flush yet, if you follow the recipe and advice given in this forum, you can't go wrong!

Thanks.
