My husband has been diagnosed with being hyperthyroid. I have been trying to do some reading on it so i will be able to understand more. He is currently on tapazole and propranolol. Since beginning the tapazole, he has been having major mood swings. He realizes that he is having them but doesnt seem to try and control it, or maybe he cant control it. I am at a loss of what to do. I dont know what to say to him because i dont know what type of mood he will be in. He can have several ups and downs within one day. If anyone has any information please let me know. I dont know how to handle it anymore. Thank you so much.
