if you are not already doing so, i would add oil pulling.
iodine definitely opens up elimination on the micro scale. that is why keeping the large channels open is so important.
the amount you are taking is safe. Iodine has an action on the body as if one were fasting. this will also cause a covered tongue. while taking Iodine you should be able to control thrush and candida with diet.
you could also play around with the other protocols that accompiany iodine. the most important of these i have found is the salt. you might try gargling with salt water, and old classic that stands the test of time. i am very interested in hearing about the recent Iodine conference. citingsources has hinted that B2 is being added as a standard for OIS. waiting with baited breath for that info.
