What my suggestions may be is to learn to provide your body with the needed Alkaline Minerals so that the Acids in your body and the Acids in the food which you may choose to eat may have enough Alkaline Minerals to react against to provide for the production of Electrical Energy Release so that your body may operate!
This also means that you may want to take extra Calcium of some form to react against the Acids so that you may get Electrical Energy Release from Calcium!
The Vit D may be Acidic, which may be why it helps the body to get Energy from the Calcium thru getting Sunshine, so it may be that if you provide your body with proper Digestive Acids, that your body may be able to utilize the Calcium!
It is best to get some sunshine, but if you are unable to do so, then you need to find a way so that your Digestive system may Create an Electrical Energy Release from the Calcium without enough of the Vit D!
The time to eat high potassium foods may be in Hot weather!
The time to eat high Sodium foods may be in Cold weather!

Yes, the clay baths may help pull the Acids out of your body, if the clay is high in Alkaline Minerals!
You say you cured your hyperthyroidism, yet your thyroid is still giving you problems, "SO" how could you have cured the problem?
Why are you taking thyroid hormone, if you cured yourself?
You say the red cabbage helped you, and you believe it may be because the red cabbage may contain hystamine?
Is it more likely that the red cabbage may have provided your body with some of the needed Alkaline Minerals which your thyroid gland was needing to stay Healthy, and that this may be the reason for your benefit, more than the supposed hystamine?
Do you realize that it may be "IMPOSSIBLE" for your thyroid gland to work properly or stay Healthy without enough Iodine in a Complexed form with enough Alkaline Minerals such as may be in good Quality Kelp?
You seem to have tried to convince yourself that you can not take Kelp with Iodine, so "WHY" are you seeking suggestions from me?
But, just maybe,"IF" you figure out that what you have been doing has not solved all of your problems, then, just maybe you may decide some of your ideas may not be correct?
In order to solve your problems with your Thyroid , you must figure out what your thyroid gland must have to stay Healthy or to become Healthy, when it has become Sick and Diseased as yours may have become!
Have you figured out what your Thyroid Gland needs to be Healthy?
Smile Tis your choice.
