I felt extremely tired this morning, and it was kind of hard to concentrate. My eyes kind of sting, and I know part of that is the fluorescent lights and the computer monitor, but part of that is the faux-weariness effect of caffeine withdrawal. I got a very mild headache around 1:15 this afternoon. I still have it, but it’s so minor that I can’t even really notice it unless I think about it.
All in all, not too bad.
