Your post implies you believe there exists a completely risk free option. No such option ever exists! Neither your doctor(s) nor anyone else can ever guarantee you a positive/successful outcome [nor even an outcome that guarantees you to be reaction free].
My 20 years of ascorbate study [and experience] convinces me that ascorbate is the best [and least risky] modality that a person can ever try, for any-and-all negative health symptoms [as Dr. Klenner stated]. Although I can not state categorically just how ascorbate would assist the body in dissolving and/or eliminating the gallstones, I have no doubt, given enough ascorbate and enough time, it would do just that.
Personally, Margo, I would choose Bowel Tolerance dosing [or “C-flushing”] with ascorbic acid, as a heath modality, over liver flushing, “any day the week.” But that's just me.
I assumed, Margo, you were looking for an alternative approach to your health situation. Surely not a “guarantee!” And I provided such [as I wrote] “as grist for your [health] mill.” You can rest assured, Margo, I will continue to advise others exactly as I have advised you, because I am convinced ascorbate is the best and lowest risk modality they can choose for any-and-all health issues they may be facing.
You have my best wishes, Margo, for a successful resolution to your health issue!
