Did Nyquil make me high?

So I'm feeling a bit under the weather so I looked around the house for all the over-the-counter medications we have. I found Nyquil and took the allotted amount. Only after taking it did I realize that it was for night-time and for helping you fall asleep. However, it was about 3pm and didn't get tired at all. In fact, I just got hyper. I also started to feel somewhat absent, like I was dreaming. I've never done any drugs, so I don't really know what it's like to be high. Anyways, I was wondering if Nyquil really made me high or if I was just in a funk from being sick. Thanks!
