Cough
"DO NOT TRY IT. I know some of you have had good experiences and some have had bad ones. There as been more bad ones then there are good I know that much.  I took this medicine for my dry cough that I was having, I felt fine for a little while, went to sleep. And then about an hour after going to sleep I woke up in a full blown panic attack. I felt like I was going to black out, I kept having hot flashes, and severe stomach pain. The feeling of throwing up was pretty bad too, but it never happened.  I was shaking and almost went to the hospital."
