Rowdy (I am not a doctor and can not advise as one)

If it were me, I would ask myself the following questions.

Am I taking Quinine? I should be adding that with the zinc.
Did I take the paste only once? I should doing that daily for 2 to 4 days.

I would Call my doc NOW and get a abrutal inhaler prescribed and going.
My doc may also wish to start an antibiotic.
Also be sure I am taking a daily famotidine (pepcid)
Additional antihistamine may be warranted based on what my doc suggests.

Once I've addressed those items above, it should take 3 more days for improvements to show themselves. I would monitor oxy and heard levels and if no real change continue at home treatment as discussed with my doc, perhaps adding supplemental oxygen could be discussed.

My doc should be concerned about pneumonia at this point, more so than covid.

Finally, I would explore some melatonin gummy's before bed to help with getting a sound nights sleep. I would mentally prepare myself that I must rest at home for a couple more weeks EVEN IF I am suddenly better tomorrow, my goal of "return to work" is no longer my immediate goal. My thought process is one of rest and recovery only.
