A chocolate cure

My rebellious nose didn't behave too badly today at work: it wasn't that congested and I didn't have to blow my nose too frequently. But an hour after eating supper, my nose got stuffy again and I was beginning to feel irritated because I couldn't breath easily. So I tried sucking on some candy and taking frequent sips of water. This has always worked with me but not this time. Then much later I had a yen for some chocolate so I got one piece of Bacetti (we have a whole bag given by a family friend working in Italy) from the fridge and ate it. Surprise: my stuffy nose cleared up! And it has remained clear until now, an hour later.
