Eating

He was prone to suffering anxiety attacks over responsibilities both minor and major, and during these attacks he found that he didn't like to eat, or rather that he didn't like the satisfaction that came with eating. He would eat only enough to calm the roiling protest of his stomach, and he found this act of self-denial engendered an internal reaction within his body. He felt more alert, active, perceptive when he ate lightly; his body perceived the reduction in food as a threat to its existence, and it responded by actively engaging nerves that were typically responsible for only reflexive actions such as breathing and digestion.
