Not enough info: 1st, there are many "Nyquil" products available so it's not clear to me which you took. Of note, most newer antihistamines (like Xyzal) can still interact w/older ones (like diphenhydraine) by making you sleepier. However, even more important is quantity consumed, since it's possible to overdose w/either. Best to call Poison Control w/details. Or go to ER. Check out http://goo.gl/d6NHg6 for info
