# Yerkes-Dodson Law and Drugs

According to the Yerkes-Dodson Law, there is optimal point of arousal and performance. Suppose a person takes a stimulant such as Adderall. This would increase his arousal. However, it may increase his anxiety (e.g. side effects). Would combining a "downer" (such as alcohol) with an "upper" (such as Adderall) maximize productivity? This is assuming that at a baseline level, a person cannot maximize his productivity.
