To really get the stones out you better stick to this flush. Believe it or not after awhile it becomes a regular day, my main thing is that I know I need a bathroom the next morning.
You might consider drinking enough water, though you won't get out a real BM, you will get buttpee. The good thing about that is that it is easy to see the floating green "peas".
Often when people don't feel well it is because they did not drink enough. http://www.curezon.com/forums/m.asp?447&i=23455
I would also suggest to do the flush every 3 weeks so you get in a routine and it does not become such a big deal.
