Three out of four flushes produced stones,....those are GREAT odds! (I do know how FRUSTRATING the not-so-successful one's feel however). Yes, perseverance is a dying characteristic these days by in large,....but not with those of us fighting for our health back or our lives! This feeling 'puny' stinks on ice, huh?
You have an awesome attitude,....which means you have EVERYTHING you'll need to accomplish your goal.
I'll be there running for the finish line myself friend! :-)
