I went for my cardiac stress test today. I'm so tired now!

I also slept for just 4.5 hours. Although I'm usually reasonably functional, I'm falling asleep so quickly today.

I had a hard time with the test, but they said I got to 85% of my max heart rate, which is exactly what they needed.

I have the echocardiogram next week.

No change in how I'm feeling and other stuff, but at least I'm drinking a lot of water (I guess that can be bad, too, but I'm adding salt to whatever I happen to eat).
