Sorry newbie speaking, diagnosed about three weeks ago. In 3 weeks I haven't slept more than three hours and I wake up covered in sweat. I spend all day catching my breath and then i read about people that have lived with this for years. I can't walk upstairs without stopping i'm not eating and my question is how do you do it? My pulse rate is at worst 170, though it fluctuates, I'm sure you get the picture. I'm on digoxin and bisoprolol but they are are not helping at all. At the risk of sounding all dramatic, what do I need to do to, because this isn't living.
