Demon coffee

I'm not sure when I got it into my head that I wanted to kick caffeine. But it was at least a month ago. And I thought, "Oh, I'll wait until I move and get settled". So Sunday I thought to myself, this is the time, since I am moved in and more or less settled. I assumed it would not be that bad, since I only have a couple of cups of coffee a day, in the morning.

Day 1 - Monday. Everything seemed fine. 'HA! This will be easy!' I think. Foolish me.
Day 2 - Tuesday. Still Ok, but I feel a bit sleepy in the afternoon. Suddenly at around 10 pm I get a bad headache. Still, I sleep really well, and think 'If this is the worst of it, I'm set'.
Day 3 - Wednesday. I feel like a bucket of crap. I sleepwalk through the day, fighting the headache. I take Ibupofen, which does not work, because the codeine tablets also have caffeine in them. I give up and go to bed at 10 pm.
Day 4 - Thursday. (Today). Dear God, I feel like a truck has hit me. Seriously. I slept for 9 hours straight, have a blinding headache, and could easily go back to bed. But my parents are coming here today, and we have plans! I don't want to be a zombie today!

So.... I gave in. Yes, I am having coffee. I will try to stop again on the weekend.

Sigh.
