What specific ingredient in night time cold medicine would keep me awake?

Question

The past few years whatever I take wires me bad. Nyquil and Dimatap(spelling?) is bad. And something else I took my husband said works great for him, I took once. I just lay there all night, feeling wired, and not sleeping.

Do you have any idea what the ingredient would be that I need to stay away from?

Best consult with your MD about this.

Answer 2

anti histamines can keep you awake.  Usually night time medicine has less of it or non of it.
