I was told through a telephone appointment. I get breathless, shaking and heart racing when I exercise (reason for seeing Dr in 1st place). I have small children and I work in a school. I am worried about compromised immunity and because I am over weight losing weight is no bad thing, however I am concerned if I don't take the drugs I might be doing my body some long term harm. The dr said it was my decision. I am tempted to wait until my endo appointment (no date for that yet). People's thoughts on?
