From reading your message I understand you have combined the Epsom Salts with a pint of olive oil and lemon juice. Is that true or have you followed the 2 cups of Epsom Salts in the evening followed by half cup of olive oil with juice before bed, followed by two cups of Epsom Salt in morning/afternoon.
Reason being, It seems that those who swallow a full pint of olive oil every 15 minutes seem to expell more stones.
If the above is true I would like to hear from you as my partner and I are in the process of our second flush today and would welcome a more successful flush.
