It started on Tuesday in the Test Kitchen, when I took a bite of bucatini with fresh tomato sauce. It was absolutely delicious until, oddly, it started tasting slightly bitter. I had a heaping portion of tuna-noodle casserole, which was supersatisfying...until the bitter flavor returned. I headed to a wine tasting—one with hundreds and hundreds of bottles out to try—but I only lasted a mere 45 minutes because no matter what I tasted, there was that weird medicinal flavor in the back of my throat.

When I returned to the office, I immediately turned to Google. The more reliable medical sites said I could have anything from reflux (I had no heartburn) to lead poisoning (not likely) to cavities (quite likely). I decided to sit tight and see how I felt in the morning.
