When I fisrst started flushing , because the symptoms were pretty severe, I did a series of LFs every 10 to 14 days, and learned quickly that taking the OO/GJ mix can be a bit trying, but sucked it up and continuesd as I was getting results...
(Had to slow down as I got some horrendous allergies; couldn't open my eyes, etc)
What helped me, as all the prepping takes some effort,
was to start "double flushing", where you take another dose of OO/GJ 2 hrs after the 3rd ES and then follow up with the 4th ES.
This way, if there is something in the gallbladder or the bile duct and it doesn't come down the PM OO/GJ dose, you'll get another chance in the AM...
I've had great results with that....
I guess it come down to: how badly do you need to flush?
Also, make sure you prepare so you make it easier for the stones to come out.
I find using Magnesium Malate very helpful (have a hard time drinking all that apple juice).
