There is no reversing the situation. Basically a fully functional perfect gallbladder has enzymes that keep crystallization from happening to form stones. Even when you are fasting, the enzymes should do their job. So mine isnt so perfect. It is possible that while fasting, it allowed the chemicals in my gallbladder to crystallize and form stones. Perhaps on a normal basis, things are moving and flushing enough that it doesnt have time to form. So it is VERY possible that I get another attack down the road. But next time, it will be under normal circumstances and at the point, I will recognize it as an on going problem and take steps to correct it.
