Hi Pauline,
I have done 7 flushes to date.
Don't be despondent, for my first few flushes all I passed was grainy/sandy stuff.
This used to upset me, but now I know that it was all in the way my body coped with my congested liver/gallbladder area.
I now pass stones.
It took a long while to open the congestion, but it was worth it.
By the way, number 8 flush is starting tonight.
goodluck with your next flush
Don't give up.
regards
Marg
