Went back to the doctor yesterday. He prescribed a different antibiotic and a much stronger cough syrup. Yeah, cough syrup. I didn't think too much of it at the time. After all, it's mostly treating a symptom. Being of a technical mindset, I know in my bones that you want to go after the root causes.
Ahem. Perhaps this is not the entirety of treatment.
The fancy snake-oil has already made a difference. A big difference. The last few weeks, I have been remembering dreams much more than usual. In hindsight, that's a sure sign of not getting deep sleep. I took some of the hydrocodone-containing cough syrup last night and slept like a log. I feel much better this morning.
The doctor said I might not have been sleeping too well and that the stuff would help; I took it for the usual rah-rah talk. Guess again!
