I was in auto crash-just couldn't get well. Refused to take anti-depress. and nerve pills Dr. prescribed and set out to find what wrong with me. I went to new Dr. whenever told "just have to live with it." About 12 years later I went to new dentist for reg. cleaning and told them not want fluoride treatment. Dentist gave me massive fluoride directly on teeth. Later that day I had flu symptoms, extreme weakness, coughing, then neck & heart pain, rib dagger-like pain (gained 25 lbs in about month). Was diagnosed hypothyroid, prescribed dulse or kelp liquid. A blessing in disguise. WELL NOW!
