Not a good idea: Nyquil has an antihistamine, cough suppressant and acetaminophen. You are already taking Cetirizine (zyrttec), so why mix medications? Why not take a whole Cetirizine to begin with? Do you really need the other ingredients?

YES: however the use of both products should not exceed the doses you are using and you may have increased sedation.

Yes you can: but better hold the next dose of zyrtec (cetirizine) while on the nyquil until you are done with the cold episode,
