Minor plaint

I want cake. I spent a very long time writing an e-mail, and I have an exam in the morning, and I have lab after exam, and who knows how many lectures. Also I am sleep deprived, emotionally wonky, and haven't gotten exercise today (snowing too much to go to dance practice, and my cranial tibial muscles hurt from overenthusiastic elliptical workout yesterday). I am struggling to finish going through the notes for anesthesia.

And I want cake.

*sigh*

Okay, back to opioid receptors.
