Read Freya's posts. I was like you, very 'concerned' about everything until I was to the point of giving up. She's done around 50 flushes, she's very kind and she knows what she's talking about.
Aunte is right too about the Ultra-phos being too strong. I'm surprised the doc prescribed all that. Like Steve said, you don't need all that.
Just apple juice alone will work. It made me feel very "congested" which I assume was from swelling, or softening, the stones. But the pain of that congestion is worth getting all that toxic waste out of your body!
I'm a newbie too. Only one flush, so I'm giving you my limited knowledge and parroting what I learned in here from the experienced flushers.
It's really not that bad.
It's amazing how I was less worried about getting my gall bladder out than I was about doing a liver flush! I'm ashamed to say that now, but I hope it helps someone. It sure helped me open my eyes to how backwards our faith and fear is. We need more faith in ourselves and more fear of the so called professionals.
You're on the right track. You're in the right forum. Relax and enjoy your journey to not only cleansing your body, but taking your power back!
