The allergy/sinus theory did not work out – or at least Zyrtec did not fix it. Interestingly, most all my dizziness – or I should say sense of instability – comes when I am running or walking downhill. Not much when going uphill. Signal? Noise? Who knows?

Meanwhile, ECG came all clear. Will see if the doctor wants me to check the arteries next.

But before that, coming up next – full vision check day after.

The root cause analysis continues. My head is still around something gone awry between by ears or eyes.

Meanwhile, I am sneaking in the running miles, all the same!
