Hey Pepe you sound like you're flyin' high! woooooweeeee! Glad to hear...exciting that it looks like you're coming to the end of your stones, too. yip!
So..the current wisdom is: stop taking the b&p's on the day of the fasting and flush for sure. I have resumed the b&p's the next day by evening...but it's said that you might want to take that day off too.
