I've done flushes at various times. Even did one where I sat up instead of laying down the first half hour after drinking the oil/juice. Got good flush results there. Having done over 20 flushes (not all of which expelled anything) it seems to me that the most important issue is time between flushes not which recipe you use. Your experience may be different but I think that if you don't allow enough time between flushes, stones haven't moved forward enough to be expelled, it wont matter whci flush you use. Even though I have done over 20 flushes, I still have symptoms so I will get going. Some things just take time. I improvement has been slow, but steady and very evident.
