I believe I have hyperthyroidism due to a few things, lost about 35 pounds in 6 months, I have developed sporadic mood swings within same time frame, I have noticed what seems like very bad bags developing around my eyes, I get shakes, I get blurred vision, I m tired all the time and sleep for 13-17 hours a day (completely uncontrollably) I m weak, but I eat A LOT and I eat very healthy, aside from an insatiable craving for salt which I eat even just by itself these days (I never even used to cook with or add any kind of salt to my food) my thyroid is very swollen. does smoking affect me? and is this the reason for my salt craving? is there anything I can do to try to manage this before I see the doctor in 3 weeks?
