What is this hangover thing you speak of? Oh that's right. The poor physical condition of mere mortals the day after getting a good drink on. I have never had a hangover, and when I do drink it is seemingly with the intent of commiting suicide by alcohol. Oh I might feel it, slightly. My reflexes being a tad slower, and a craving for bacon, eggs and a pint of water. But delicate stomachs, headaches, all the normal maladies for a hungover person? Never felt them.
So, to all mere mortals: Nyernyernyer!
And to the OP in particular: Congratulations. You are now one years closer to the inevitable failure and decay of your meaty husk.
