I do feel really tired. Had to do a doctor thing and couldn't eat or drink all day until the appointment was over- naturally it was scheduled for 1pm instead of right in the morning.
Not eating is fine, but not being able to have some water or caffeine sucked. I immediately went for food at the first place I saw. Holy shit, it was TACO BELL!
But the line was too long and not moving, so I had to settle for Arby's. :'(
