The confusing is that Epsom Salts is magnesium sulfate.
If you want to cut back on the ES take it at least once
just before the oil etc.
Some people have used saltflushes or Oxypowder afterwards
but that is their choice. Andreas Moritz says very few people are allergic and can use magnesium citrate instead.
Since I did a lot of flushes I added a dropper full of
stevia in the ES water.
I still do that when I think my gallbladder might act up and it works after 15-20 minutes the symptoms are gone.
