Hi smile. I have done about 3 cleanses without Epsom Salts before I discovered Hulda Clark . Basically the E salts just get your bowels moving and supposedly open your bile ducts. My first 3 cleanses were straight olive oil with lemon chasers drunk slowly over 2 hours. I have also done one where you have a litre of freshly juiced organic apple juice mixed with a splash of olive oil every day for a week leading up to the olive oil/grapefruit juice drink.
Those first cleanses were my most radical (my GB was totally block and making me very ill). So I suggest you experiment and find the way that's best for you. If you only take 1/2 cup oil then bowels probably won't move as quickly as when you take Epsom Salts , but they will move. You can also do an enema if you get sick of waiting for stuff to come out! My first and second time, I actually took 2 cups of olive oil! (4TPBNS every 15 minutes chased with a mouthful of fresh lemon juice).
The grapefruit method is easier to get down so I do it that way now but I take 1 cup of olive oil mixed with 1 cup of grapefruit juice.
You can also take less Epsom Salts . Then there is Magnesium Citrate mentioned in other postings and I think there are even capsules.
So don't let ESalts put you off! They are not essential and I am living proof.
