I personally think you need to wait a week or even better, two before trying again. Even if you did not pass any visible stones, you probably have put some stress on the liver.
Are you the person who wrote they put the Epsom Salt in capsules over on the liver forum? (I am terrible about remembering names) If so, the next time try taking the ES dissolved in apple juice or cider. It may be that the capsules did not dissolve all at the same time, or perhaps you just absorbed the magnesium. The one time I tried putting ES in capsules I had poor results, but, I do realize others have had success with that practice.
Meanwhile, try taking a little good quality oil every day, preferably olive oil. Avoid fried foods, especially at fast food places where you don't know the temperature or the quality of the oil. Avoid all trans fats and cut down or eliminate dairy and meats. This practice should stimulate bile production, but not clog the liver further. There are a lot of variables when flushing, don't be discouraged, your next flush may be the mother lode.
