「おくすり飲んで寝よう」(Take Your Medicine and Go to Sleep) is a VOCALOID song by producer もちうつね (mochiutsune), featuring Hatsune Miku on vocals. The track was originally released as a self-titled single in 2022, with mochiutsune handling composition, arrangement, lyrics, and the accompanying music video. It joined the maimai DX library as part of the BUDDiES PLUS update on April 26, 2024, categorized under niconico & VOCALOID. Lyrically, the song paints a picture of quiet alienation, a narrator who has felt out of step since childhood and settles on the absurdly simple solution of taking medicine and going to bed. The chorus repeats "孤独でモーマンタイ" (kodoku de mōmantai, "lonely but no problem"), blending melancholy with a shrug-it-off nonchalance. A standout moment comes mid-song with a rapid-fire homophone sequence, 早々、躁だね、想像、騒だね、相当、怱だね, that showcases mochiutsune's playful ear for the sound and rhythm of Japanese wordplay. The production sits at a steady 130 BPM, balancing a laid-back beat with Miku's characteristically crisp vocal delivery. Beyond maimai, the song also appears in SEGA's CHUNITHM LUMINOUS PLUS (added July 4, 2024), where it later received a WORLD'S END chart (狂☆4) in CHUNITHM VERSE. That chart's designer credits read "パンケーキの山...!?" ("A mountain of pancakes...!?"), a playful callback to the lyric "ちっちゃなオトナがパンケーキいい気" from the song itself.
