Chest pain and lungs collapsing and cancer, oh my!

I started to quit smoking today. It's currently 2:11 PM and I haven't had a ciggie all day.
Aggitation at nothing is coming up and down in waves. Right now it's OK, half an hour ago it was rather hard to control. I hope nobody asks me to do anything if it comes up again. I don't wanna be a cunt to anyone needlessly.
My head feels like it does when I have a big night drinking and wake up early, but with only a slight headache. It's fucked up.
It's taxing for me to hit the correct keys. Actually I'm missing heaps. I've lost the ability to predict where the next finger should be placed in order to enter the character I want.
Gah.
Smoking sucks dick, boys and girls.
