I get very tense working, so I often have to get up and wander around the house. It is very bad on my stomach. I have to be mad to be working well anyway, and then I am mad about the way things are going on the page in addition. My ulcer flourishes and I have to chew lots of pills. When my work is going well, I am usually sort of sick.
