My son began the flush recipe on Saturday and finished it on Sunday. He began having small green stones come out all Saturday afternoon, but he took his last epson salt at noon. Then at 1:00 a.m. on Monday he released one dark tan quarter-sized stone, and 4 almost dime sized stones. At 11:00 p.m. that evening he released a green dime sized stone. The diarrhea lasted over 24 hours too.
