Have you dont the Iodine loading test? If not than your duration on means very little. Even if you did reach full sufficiency at 6 months it doesnt mean all the damage done by being deficient has been repaired.
Dr Brownstien has said for his patients its usually 6 to 12 months to reach sufficiency, and after that additional time may be needed for full healing.
People need to have some patience, your not going necessarily to overcome a lifetime of deficiency and toxicity (decades in many cases) in just a few short months.
