Drowsiness is prevalent at what blood alcohol level?

Explanation:
Drowsiness appears as a prominent sign when alcohol has sufficiently depressed the central nervous system, which happens at higher BAC. Specifically, around 0.15–0.20% (150–200 mg per deciliter) the sedative effects dominate: noticeable sleepiness, slowed thinking, and impaired coordination become common. At lower levels you may see impaired judgment or motor skills, but not the clear drowsiness described here, while at levels above about 0.20% the risk rises for more severe CNS depression such as stupor or loss of consciousness. So the 150–200 mg% range best corresponds to drowsiness prevalence.
