Yesterday I took an anti-histamine, which meant that in the afternoon I was really drowsy and had to warn the karate teacher that I might be a little unfocused (I did alright, though, I think). Today I didn’t taken an anti-histamine, though I probably should have, but instead I seem to be reacting to the changing athmospheric pressure or something. I’ve had this almost-headachey feeling in my forehead all day, and my eyebrows keep twitching uncontrollably whenever I look at the screen, which makes it darn difficult to concentrate. I’ve succumbed and taken pain-killers, despite there being no actual pain, just a vague discomfort, in the hope that it will help in some way. So far today I have edited one (1) line of code and spent ten minutes explaining how a function works to one of the guys in support. Unless it clears up in the next half hour or so – which would allow me to put in a good, oh, 90 minutes’ work before I go – the day will have been a complete wash-out. Not good. One of the guys in the office is 60 today and there is cake. I don’t want any. That’s how icky I’m feeling.
