Oh my! How lucky you are to still have your Grandma! I wish I had one, can I share yours? Ha ha. My Mother will be 77 this Fall and she hasn't been able to get around and shop for years, so your Grandma must be in very good health :-).
I thought that the burning meant it was toxic. But I did read an old post on the archives where Spirit told someone it burns because the juice is not getting digested properly, or something like that.
Yes, I've read Julia Changs site, but it's been a while. I spoke with her on the phone a few times too, what a nice lady, and she loves to talk!
That's too bad your colonic lady is so far away. I am blessed to have found any near me. I live in the southeast where it's sure not very progressive when it comes to alternative health. Anyway, good luck on your flush tonight, and yes, let me know how it goes. I do hope I see some real stones this time with mine.

when you said " and not just stones". What else comes out?? Just curious :-).
