'Don't do it, Rachel.' 'Do it; it'll help you sleep.'

Rachel was struggle with these conflicting desires -- voices -- while lying in bed at almost the half-hour mark. Maybe I'm a doofus, but don't do what? Either the inner voice was referring to taking the nerve pills her boss at the school told her about earlier that day or it's talking about the 'm' word.

Insights anyone? Thanks.
