keep a list in Workflowy of minor medical issues. It still doesn't feel worth the hassle to go to the doctor for one thing...

That seems like a great idea!

I have found that compiling written notes of one's medical history (including not only observations about how you feel on given days, but also notes you have taken during doctor's visits), can be another helpful thing to do. At least for me, this is largely true because it can be hard to remember the particulars of why a particular diagnosis or treatment was given to me five or more years after the fact.
