Hello, new to this so don't know if I'm posting things right. I had a total throidectomy a month ago and I'm still feeling real bad. I'm so tired, ache, weak, shaky, heart rate goes up, irritable, etc. I go for my first blood work tomorrow and don't know if I should take my medicine before or after?? I was put on 100mcg of synthroid. If you were still hyperthroid would they need to increase or decrease the medicine??? Someone please help me!! Thanks
