Later: I did go back to bed and doze off.
I had a quiet day, and ended up sleeping a lot of the day. I talked to Dr. C. in a telemedicine phone call about my allergies and asthma. He agreed with my feeling that the coughing fits and wheezing I've been experiencing were most likely due to those causes, especially with my history of such being well-established long before the pandemic. "Asthmatics know their asthma," he said. I used my nebulizer in the evening, and that seemed to clear things up a good amount.
