"If I don’t sleep at once, chloral, the modern Morpheus"

 Chloral hydrate is a hypnotic drug that was used in the 19th and 20th centuries to induce sleep.  It was also used recreationally, despite a variety of adverse effects ranging from rashes to cardiac failure.

In Greek mythology, Morpheus is the god of dreams.
