I have been so tired lately because my TSH level has been up quite considerably. A 'normal' TSH lab result is between (roughly) 1 - 4.5, depending on the lab. My 'normal' range, meaning I can get out of the bed in the morning is anywhere between 0.1 and 1.5. At the moment it's 2.33 and I feel like a zombie. I need to increase my T4 dose to level it out.
