Etymology: This word is an inflected form: the plural of "sleeplessness," the state of being unable to sleep. Its base is a compound-style formation, "sleepless" plus the suffix "-ness." "Sleepless" is built from "sleep" and the suffix "-less," meaning "without," so the whole word literally describes a condition of being without sleep. The suffix "-ness" traces back through Old English "-nes" to Proto-Germanic "*-assuz" and beyond, where it formed abstract nouns of quality from adjectives. English has used it productively ever since, so "sleeplessness" is a transparent, unremarkable coinage from existing parts. The plural form "sleeplessnesses" is rarely needed, since "sleeplessness" is normally uncountable. It appears when a writer wants to treat separate episodes of sleeplessness as distinct instances, as in "the nights of sleeplessnesses that followed the diagnosis."
