Great testimony joiejoy : ).
Fasting is a highly worthwhile lifestyle to come into for so many beneficial reasons.
My opinion about the Gallstones
is that if the gallbladder was filled with them and could no longer contain them, i would be surprised if a 10 day fast autolyzed all of it, but enough was accomplished to temporarily calm the tensions. I would highly recommend that you google into the gall bladder flush, and plan to do it soon. it's an olive oil / grapefruit juice home remedy mixture that you drink right before bed and some other simple preparations leading in. It's also a good way for you to know how full or empty your gallbladder is with them.
I did a series of them several years ago, once per month. The first time i got a whole handful (estimated) out. Next month, a half handful, the next, a quarter handful, the next an eighth of a handful, the next about a 16th, then the next time there were none and i knew i was clean :).
So much better than having this highly useful bile producing organ cut out of our bodies by the mainstream medical folks, most of whom would tell you that the gall bladder flush is quackery.
