Yes there are ways to get more stones.We all use different tricks.
You can
-warm your gallblader with a hot water bottle
-fast on apples or applejuice for a day or two before
-increase the amount of oil
-zap
Read back and you will see all the different things people try.Just use common sense.I have done many flushes where I got over 500 stones.Maybe you don't have 2000,we're all different.
Sounds like a great first flush though.(I got 1 stone on my first)
