I have read 3 post here from people that took valium and they said it was a big help. Someone else said we shouldn't take any medications. I don't sleep at all doing a flush, may nod off a while but thats it. I found after laying on my right side for about 2 hours, if I stretch, lay flat, then go back to the right side, I get a gurgle and presto, I dump more stones. But I also massage the right side, from right to left helping the gallbladder along. Some say they jettison their stones within the first 30 minutes, but what I'm finding is the big one for me is about 1 1/2 to 2 1/2 hours into it. Each flush, and I've done 3, I get about 100 stones.
