When I was first put on meds for Graves I was put on what I now know, way to high of a dose. When your resting heart rate is 40 and you are fighting falling to sleep on the drive to work and your hair loses all of its luster and falls out, you know there is a problem. That is when I quit weighing at all. It was so discouraging. In 2 months I put on about 20 pounds and the weight gain continued for another 6 months. After that I stayed off the scale because it was depressing me. For me, getting back to daily weighing was my signal that I was ready to do something about my weight. I understand fluctuations and my weight is actually very steady and always has been from day to day so I trust this measure.
That is me, if it bothers you, stay off.
