I am wondering how cytomel may be beneficial to me. I have a friend who has Grave dx. She told me how she had been feeling achey in her joints, tired, never getting enough rest even when doing so, never having any energy. She was perfectly describing me. She started telling me about cytomel and it's effects and how the body uses it as T3. I feel I am missing out, because I am not taking this. Should I be using this in conjunction with my Levoxyl 88mcg?
