How long does it take to have a BM w/ liver flush?

My husband and I did the flush last night. We took the Epsom Salts at 8 and 10pm, with the OO/juice drink at midnight. We took the final two Epsom Salts this morning at 9:30 and 11:30. It is 12:50 now and my husband just started passing stones. How long before I have a bowel movement and/or pass stones?

Thanks!
