I was thinking about radioactive therapy for Felix's hyperthyroidism. Does anyone know anything about this? I don't mind giving him his pills twice a day but I'm afraid this terrible thing has robbed us of more years together. How long should I expect him to live if he's only taking tapazole for his hyperthyroidism? He was diagnosed about 6 months ago and I don't know how I feel continuing with the tapazole long term.
