This is just my two cents, and it may not apply to you, but a year ago last fall I experienced a persistent dizziness after a Liver Flush (dizziness comes from the liver in Chinese medicine). I was afraid to flush, and so didn't for maybe 6 months or so -- anyway, the dizziness subsided, and I remember thinking I lost out on 6 months of flushing when I could have flushed again and the dizziness would have disappeared probably right away. But your problem is different, I know, and I understand your worry with the kidneys. Maybe you could try tsetsi's flush with the eggs and lime. I got really good results with that two years ago, and it's much gentler. Just do a search, if you want to check it out. Good luck to you.
