fatigue or insomnia? if fatigue, is it shortness of breath when talking or exercising?
Fatigue. I sleep all too well.
At first a half mile walk would send me to bed.
I raked a bit of the yard today. Out of breath, arms tired and heavy.
It never got into my lungs. No cough. Air exchange should be fine. Breathing feels good.
But cellular respiration might be affected somehow? Like the oxygen isn’t being used right in the muscles, ATP isn’t being regenerated?
Wild guesses.
