How is your liver? I've used a whole host of therapies and most of them have helped me make progress. Like you my Iodine preferences are idiosyncratic (mrt tested my body only wants magnascent and a tiny bit of Lugols now) and in spite of eating very carefully my digestion still has issues. But what I hadn't tackled fully was my liver and I discovered very congested liver and parasites. I'm amazed I made the progress I did with those issues. Liver has profound effect on digestion. You might have a look at the Liver Flush Forum .
