You can try other protocals that don't require Epsom Salts (magnesium sulphate) at all. I never use it! :) I just make sure to thoroughly soften the stones with apple juice and liquid phosfood or Gold Coin Grass from www.sensiblehealth.com.
And it could be that right now your liver is too weak to expel enough bile to really force stones out of the bile ducts and gallbladder. Keep trying! Don't give up! :)
Where in sweden are you? I worked a couples days there out by Jonkoping. :)
