I don't feel this mode of the flush will help you, the string flush will only help in a suitation where this is bile "stuck" infront of a wall of stones/chaff in the liver, where the liver cells CAN still produce bile, a build up of bile can break the wall.
The GB will only empty the once during ANY kind of flush, the other bile will just leave via the common bile duct and the GB probably won't get any bile during that.
Having GF/Turmeric during the morning will make the GB stronger, I would avoid too much GF because you are a pitta type? (AFAIK) -- avoid having things that contract the GB during the morning because you'll need it during the day for lunch/dinner.
Stone crushers may help this, but I think it's a cause of just waiting, the GB will become stronger over time and it may push out this final stone! :) As long as it isn't causing you any symptoms, I think you should just hold off doing anything major.
