Cheratussin AC and sleep

Just took first dose and hoping it works, I'm coughing like crazy and can't get anything out and can't sleep at night cause the cough keeps me up, I'm curios about this Tussionex, is it appropriate for me to ask my doctor about using it instead if this doesn't work?

Unfortunately, I was not able to sleep at all, all night. Took my second dose at nighttime, about an hour before bed, and I layed down, closed my eyes, and layed there for hours with my mind racing. I was not asleep at all. I didn't have nightmares or bad dreams, but I couldn't get to a point where I was sleeping either. During the day, I didn't seem to have any adverse reactions. I think I'll avoid prior to bed in the future. Good luck.

I don't recall having any weird dreams or nightmares. I've been taken this syrup for 3 days now, when I wake up, a couple times during the day and before I go to sleep. It's doing what the site said, it's loosening up my mucus crud and I cough it up and spit it out. Mostly in the morning, like I'm coughing up a lung. I'm still coughing and I hope I get better soon.
