Hi Vera,
Everyone feels apprehensive before 1st flush.
You will be amazed when you see the stones in the toilet.
It is good if you have an old collander to place in the loo and catch the stones.
I am truly amazed at what I have passed during my 12 flushes.
Good luck, and relax, you will do well.
you have a lot of good support here at Curezone.
regards
Marg
