Even if your are late stage with only a short time left, do not panic.
Do not fear the iodine. There is a simple safe method.
Paint the bottom of both feet at bedtime (about 4 drops of Lugol's to each foot). The Iodine will absorb into the skin and body will only absorb as much as it needs leaving the rest in the skin. Do this nightly until the feet still show a stain in the AM. Reduce the amount used when the feet are still stained. This is referred to in many old medical textbooks.
Be sure to alkalize. Alkaline vegetables help but may be slow. I have used a mineral water drink myself that works great.
Essiac tea is known for its alkalyzing properties.
