You should listen to your body. I was impatient too when starting this journey and flushed every week for 8 times in a row. Got something out each and every time, but I have no idea if I got out more stones that way. I would just get this nagging feeling when a week had passed that told quite clearly my body wanted another flush. Then, after 8 flushes I felt I needed a longer interval, so I changed to flushing every two weeks as recommended. Had no ill effects from weekly flushing, but everyone is different.
