You must understand that Iodine is a daily requirement for our health, in the same category as required vitamins, minerals & food. So, yes you will want to take vitamins, minerals & Iodine daily for optimal health. You will not become dependent on iodine.
The reason for taking high dosages of Iodine is to detox the cells of our body. Every cell in our body has an iodine receptor that has been taken over by the toxins of bromide, fluoride & chlorine. It takes most folks a year to detox the trillions of cells in our body: http://tinyurl.com/iodine-and-halogen-robbers
After you have detoxed and become iodine sufficient (90% of the cells in your body have their fill of iodine) then you can reduce iodine supplements to a maintenance level of 12 mg daily.( or else eat a LOT of seafood & seaweed ) Seafoods are not recommended because of contamination.
Sorry but you cannot "Eat & drink Everything" if you want optimal health. That doesn't even make sense.
I can't make any promises that all of your symptoms will magically disappear. I can say that iodine will help boost your health and detox your body. Optimal health is not cheap nor is it easy. We have to work at it.
My worst Candida Symptoms were severe constipation, prostitis, and Asthma. All are now cured, with many thanks to iodine.
Iodine is not a cure-all. It is simply a required mineral for our immune system & optimal health to prevent the listed iodine deficiency diseases.
