doxylamine

Drowsy allergy pill

Doxylamine is an antihistamine used primarily as a sleep aid and to relieve symptoms of allergies and colds.

It causes marked drowsiness, which makes it effective for short-term treatment of insomnia but problematic when alertness is needed.

Available over the counter in products like NyQuil and Unisom: The doxylamine knocked me out for twelve hours.
