A reversal design (also known as an ABAB design) would be most effective in this scenario because it involves observing the behavior (insomnia) with the habit in place (watching exciting television shows), then removing the habit to see if there is a change in the behavior, and finally reintroducing the habit to see if the behavior (insomnia) returns. This design allows for a clear demonstration of whether the habit is causing the insomnia.
