I feel like you LN.
I wish there was a test to know when we are sufficient. Since we got overloaded with the other halogen in our daily life, it would then just a matter of finding the right amount of Iodine to keep ourselves in balance.
I feel my fluoride came mostly from years of prescription drugs, since I have not had fluoride in water for more than 40 years.
The bromide I might have gotten from bread etc. but I don't eat that anymore.
I have no plans at this point to take more than up to may be 150mg Lugol/Iodoral a day. Leave the 1000 mg up to the more knowledgable (daring) people.
