Clementines - the devil's fruit

I have a canker sore. It is driving me crazy. I have been grumpy and irritable for 2 days now. Eating (which I love) is so painful - it's like torture to me.

In doing some research in what causes these blasted things, I headed to my trusty friend Wikipedia. I learned that the exact cause of them is unknown, but included in the list of factors that provoke them is citrus.

I guess the 3-5 clementines/day I have been eating for the past month were a bad idea. Who knew? I've been addicted to them. They are so sweet and easy to eat. And I thought fruit was supposed to be good for you?!?

Ugh - learning lessons the hard way sucks...
