@burcidi-- Have you started seeing cherry angiomas (little red spots) on your skin lately?
If so, you might have bromine poisoning. Anxiety and thyroid problems are also symptoms of too much bromine exposure. One reason for hypothyroidism is not enough iodine. Iodine and bromine are similar elements and it has been shown that bromine can prevent the use of iodine by the body. This can eventually result in thyroid problems.
Bromine poisoning doesn't necessarily have to cause dizziness, coughing and vomiting. Those are symptoms that occur when there is severe poisoning from a large amount of bromine suddenly. Poisoning can also happen over a longer period of time and slowly.
