Restlessness
Although hyperactivity is often less obvious in adulthood, people with ADHD might still be rather restless or fidgety. They might pace while standing and change positions usually or fidget while sitting. Also, these people tend to avoid sedentary work or activity and have difficulty relaxing such as reading or watching TV. Instead, they always try to seek some constant stimulations like meeting energetic friends or driving quickly because they would feel very uncomfortable when being still in an extended period. Thus, falling asleep at night can be hard with a lot of thoughts. [5]
