If you have too much bromide displaced by Iodine it's possible to experience altered mental states. Before bromide was removed from many medicines, 5-10% of people admitted to mental hospitals had bromide toxicity.
You can Google this subject more. The US Army had this problem as some of the Gulf War soldiers reacted badly to a nerve agent vaccine containing bromide. The Army had to salt them out. They used saline IVs but you can use the salt loading protocol and stop Iodine until the bromide clears your system. http://www.breastcancerchoices.org/drshevin
