Yes: The antihistamine in NyQuil (doxylamine succinate) will provide the side effect of drowsiness. Like all antihistamines if it works tonight for sleep you develop quick tolerance to it as a sleep aide. Also, if you don't need the other ingredients, I would avoid taking NyQuil just as a sleep aide. For insomnia issues - cognitive behavioral therapy is the best treatment: see www.shuti.me
