Flush every couple of weeks untill you get your first no-stone flush. A least three -four times.
Do parasite clense. Flush again regularly untill no stones. Sometimes two flushes is enough.
If something does not feel right for a several days after some flush, re-flush as soon as you can.
After that keep flushing for maitenance whenever you feel discomfort in your liver area. It is once in two - three months for me. Some people don't need to flush so often. Listen to your body and decide yourself what is best for you.
