Iodine, Iodine, Iodine for your mom..will she try it? If she is also overweight, that also is not good..all the health problems that one can get (you don't need to get them as you age I've learned)is certainly from being deprived of many essential ingredients to the good life and health we should be experiencing. I would certainly start with Iodine, and build on that!
You hit the nail on the head, with saying.."I don't know, something struck me today that Iodine is probably at the root of all this sleep apnea". There is nothing an excellent dentist that uses the holistic and correct protocol can't fix anymore!
