Vi-Q-Tuss and sleep

After taking this I found it also worked in getting rid of my cough and made me drowsy, but I found I could not sleep...I was itchy like others have noted, but not tortured by it. It was the drunk like effect that really bothered me. Even when I woke up the next morning to go to class, I felt like I shouldn't drive because the world was spinning and I felt anxious.

The worst part, neither my doc or pharmacist warned me about the intensity of this drug.

Anyone else have shoulder pain and/or rib pain? Almost like a gall bladder attack? Have taken it twice and both times have had a severe pain for a short time, helps cough though..Is this just me or a common side effect? Also the itchiness..
