Sadly, I seem to be the only person NyQyll doesn't work for. It helps with the symptoms somewhat, but, sadly, does nothing to help me sleep.
Is anyone else thinking of Dennis Leary's monologue on the topic? "The Q is talking to me!! The Q is talking to me!!"
The first time I took NyQuil, I was in college living in the dorms, I had seen Denis Leary's routine, and had been warned by friends to be sure to get ready for bed BEFORE taking it.
2 doses and an hour later and I was still awake and hanging out in a friend's room in my nightie. I have found that it can help me drop off if I take it and then go lie down, but if I'm not already in a sleeping position, it won't just knock me out.
