Hi Togepi - Hope the D from the purge has passed. Did you pass any Gallstones or bright green bile? I've have read that magnesium citrate gives a better purge than Epsom Salts but the ES, which contains sulfur,cleans out the bile system better. You may have become dehydrated and your electrolyte balance could be a little off. Some people drink a balanced electrolyte drink or sports drink and water to correct this. I use a sprinkle of salt and potassium chloride in water until I feel better. The release of toxins from the bile system also leave people feeling ill. The most effective Liver Flush programs advise doing a parasite program, then a method of dissolving hard calcium stones or a kidney cleanse before doing the LF. Even then the first several flushes may leave a person feeling ill for a day or two as the toxins are cleared from the body. And it is not uncommon for people to not pass stones on the first flushes. I started passing stones on the 3rd or 4th flush and eventually got out thousands.
