Restive

Tony despite his undercover skills, had never mastered sleeping on command. In fact, ordering him to sleep no matter how tired he was, guaranteed his restive personality would deny him sleep. He’d end up tossing and turning if he tried to follow the order. Now, he didn’t bother. He’d go into the office and work instead or if he was undercover, he’d focus on the pieces of information that he’d learned that he needed to remember.

That wasn’t to say that he was an insomniac and could never sleep. Just that ordering him to sleep had the opposite effect because it kicked in his obstinate nature and increased his impatience making it impossible for him to sleep. It was also why he hated hospitals. They were always ordering him to sleep. He slept considerably better at home where there was no one to order him to sleep and he could just sleep when he was tired.
